Normally we'd just send out a tweet about this (that's usually what we do with free app deals, so if you're not one of the almost 40,000 people following us yet, you definitely should be), but this is a good one, and it's a holiday, so we wanted to make sure you knew. Sega is feeling particularly generous this weekend, so they're giving away free copies of their Columns Deluxe, a port of the old Genesis game, for the iPhone. The game is a pretty straightforward port -- it doesn't have any extras, and the accelerometer controls are a little tacked on from what we hear, but if you like the puzzler gameplay of Columns, and you should, it's a fun one to pull up for a few minutes at a time.

Plus, it's free -- from July 3rd to Monday, July 6th, Sega says it'll be on sale for the low price of nothing at all. Sounds good to us -- sit back, put a few brats and burgers on the grill, grab a Corona (and lime, of course), and enjoy some old-school dropping block gameplay for no money at all.

We're back with another edition of Ask TUAW. This time around we've answering questions about iTunes libraries, Mac data recovery, Snow Leopard on older Macs and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

Daneel asks:

I'm running OS X 10.5.7 and Windows Vista (via Bootcamp) on my iMac 24". I was wondering if there was any way in which I could make the iTunes apps in both Windows and Mac use the same iTunes library. File access is not a problem as I've got the ntfs-3g driver on the mac side and mac drive on the PC side.

I have my iTunes library on an external hard drive. To make iTunes use this particular folder, I create an alias of the folder on the external drive and replace my iTunes folder located in Users> "User Name" > Music with the alias. iTunes has no problem with this setup.

You should be able to do the same thing in both the Mac and Windows versions of iTunes. Just set an alias of the iTunes folder you want to use in Windows pointing to your Mac iTunes library and you should be good to go.

Danielle Cassley and Jason Citron are the folks with their names on Aurora Feint, but as Danielle told us in an interview a while ago, Peter Relan is the real mastermind behind the growing Feint empire. Not only did he put the two together in an idea lab, but he's one of the driving forces behind the OpenFeint enterprise. Under his oversight, the Feint folks have swelled to become one of the major forces behind iPhone gaming (and thus, behind the iPhone's app ecosystem itself).

Netanel "Net" Jacobsson is a newer addition -- he's previously worked with Sony Ericsson on their mobile devices and Facebook on their own growing app empire, and now he's arrived at OpenFeint to help them use the lessons he's learned at the biggest online social networks around on their social software. Get the sense of how big this is yet? Relan, Jacobsen, and Citron all have pretty big ideas about where iPhone gaming is going, and as 3.0 comes down the pike and introduces a whole set of new features from Apple, they're in the best seat they can be in to do exactly what they want to do.

TUAW sat down with the three last week, and chatted about iPhone 3.0 and why it's such a big deal for developers, how they're going to approach microtransactions (carefully), and what's coming next for OpenFeint now that they've rounded up a whole stable full of developers implementing their backbone. Click "read more" to continue.

Have you seen anything like that already, where developers have said, well we thought about doing it this way, but we're going another way?

PR: Too early. The phones aren't even out yet, user experience hasn't occurred yet. I would say July, we'll get a lot of feedback once these games come out with push notifications. The other thing that's kind of interesting, by the way, is that OpenFeint is working on cross-compatibility, because if I have a 2.2 iPhone and you have a 3.0 iPhone, and you send me a social challenge, in my app on 2.2, it won't show up as a push notification, right, because I don't have the 3.0 iPhone. So we are support the concept of push notifications in the plumbing and infrastructure of OpenFeint, however on a 2.2 phone, whenever the user next opens the app, they would see a screen that is an OpenFeint screen that would have a notification saying "you've got to beat my score," as opposed to seeing it on the iPhone icon, as a number, like the Mail thing, where it says you have notes waiting for you.

So I think as a user experience, the jury's still out, because the platforms are just getting ready, right? So the key here is to say that we're going to make it trivial by continuing our tradition, which is no servers, very easy to integrate, and some big games will launch in July with push notifications and then we'll go from there.

I think, to a certain extent, the same thing will happen on the microtransactions side. It already has happened with Xbox Live -- I don't know if you remember the story of horse armor, where everyone says "how can you release a different graphic and ask us to pay for it?" Have you seen examples yet of how developers want to use microtransactions? Are they aware of that danger or are they fearful of that at all?

PR: So I think the obvious one, just because I have, as I said, investments in companies in the Facebook app space, the big reason for microtransactions is virtual goods. So any kind of virtual world, avatar apps, some of these Mafia iMob apps, you can assume that there will be virtual goods unlocking with microtransactions. That one I think will translate over fairly well, in fact Net is going next week to China, where he's a keynote speaker at Tencent's annual conference. Tencent is an Asian company which does a billion dollars in microtransactions, all of it virtual goods. So I think that microtransactions, as we see them on social networks today, will come pretty much that way onto the iPhone social network, or the iPhone gaming network.

NJ: I also think that it will actually lead to the pricing, might even drop dramatically, but those who are charging for applications are going to go free, because they're going to earn much more by making it free and leveraging microtransactions.

Yeah, if you're charging $4 for an app and can sell four levels for $1 each, that's the way to go.

NJ: The user starts playing, gets very engaged, and wants to get to the next level and make the purchase, and it's very difficult not to make the purchase if you're engaged and you want to continue the game.

PR: The thing that's a little trickier, I think, is when you have microtransactions that aren't directly virtual goods, because virtual goods don't fit the theme. But are like chapters, or just additional content in the game. Then, I think, the business model is a little trickier, because that's your content update strategy, and to some extent, the iPhone user is used to -- like, if you look at the success of Pocket God, it's a double edged sword. If you talk to the Pocket God guys, their game is one of the few games that stays in the top five constantly. It's just always in the top five. And they use OpenFeint, and they're going to use push notifications, but when we spoke to him about microtransactions, he said, I have to figure that out, because their commitment to their userbase is, every week you're going to get an update with more content. So given that he's already committed that on the current price point, how does he unlock more content with microtransactions? So he was the first to say I definitely want to do push notifications, but I have to think hard about how I could incorporate microtransactions into Pocket God. So I do think there's a little more complexity there, especially when it's not just direct virtual goods. But I think they'll crack it. I think some other people we're talking to are certainly thinking of Chapter 1, Chapter 2, Chapter 3, three microtransactions. And certainly the virtual goods guys are like no questions how they'll do it.

And there are definitely precedents for both, in terms of episodic gaming on other services. Jason maybe you can talk about this, too, as a developer -- I'm really interested in the balance between making sure that what you're selling people is worth it, or something that's not. If you're asking to pay a dollar for a gun that's just a re-skin, people won't go for that. What do you think of that?

JC: I think, as a game designer, what you have to really think about is the motivations for why people will want to purchase this content. Whether it's a re-skin or not is less important than what it will allow you to do in the game. And the reason why I think virtual goods have done so well on social networks is that social pressure is a huge motivator to getting people to do things, and if part of that social pressure results in you engaging and buying virtual content, people are much more likely to do it. I mean, if you just have another gun that allows you to increase your DPS by two points, that's not terribly interesting to anyone but the ultra hardcore gamer, and then they'll probably just be pissed off that they have to pay for it. So that's not really an appropriate way to go about it. As a traditional gamer, buying episodic content or buying level packs, or substantially new gameplay experience, fits with my head, and then virtual goods, I think, have to be motivated through social pressure.

And the last question I have is just about the future of OpenFeint. I have to give it you guys -- there were quite a few, and there still are, services poking around that want to do the kind of stuff that you're doing. And just in terms of size and influence right now, you're kind of the top of the heap. So what's next, are you planning to kind of sit on the heap and just keep things set, or are you still aiming to improve here?

PR: I think that definitely we will continue to innovate and add more services to the platform -- there's no question that it's a platform play, and that we will continue to add features and additional things. I would say two things: one is, we will publish games, always, on top of our own platform technology, that will really kind of push the borders of gameplay design around the OpenFeint platform, to sort of demostrate and lead the way. So in the last announcement, we did hint at a new game coming out this summer based around push notifications and microtransactions, where we want to lead the industry. Because we never think that by being in front today, that we will be always in front. So we want OpenFeint to be the premiere platform, we agree that today, we certainly feel like it's way up there, but we feel like you constantly have to build new product on top of your platform to really make a world class platform. Because otherwise you're just sort of opining and thinking oh, this is good stuff. So we always want to test our own platform, and expect a title this summer based on OS 3.0 and OpenFeint features.

The second thing, which is, I think we're really doing something different around the business model. Ngmoco announced their Plus+ platform this week, and it's really a publishing tool rather than an open platform, and we're pretty proud of the fact that we're sort of the biggest player who is really able to provide an open platform where a developer does not have to make a publishing deal with us in order to get access to the platform. Ngmoco's platform is hey, we have this platform, it's part of our publishing network, and if you want to publish games with us, that's how you get the platform, and obviously you know the economics of the publishing business in the game industry, right? There's revenue that has to be sacrificed there. So I think as a guiding strategy, we will never make our platform related to anything with our publishing because it's our belief that this OpenFeint thing does two things that we will always have to provide for publishers: no servers, because 90% of developers have no experience building servers, they build great console games, client side stuff, C, C++ programming, all this stuff, but they really don't have any backend experience. And two, we're not going to take rev share, in terms of publishing deals. And those two things, I think, are sort of our long-term guides. The third thing is to build our own games constantly, so we can use Danielle and Jason's game design and knowledge to say here's the kind of games we can do. So if we can do that and execute, I think, with some fingers crossed, with some luck, we'll emerge as the de facto standard, which is our goal.

I had talked to Danielle a little about pricing already, but I wanted to ask about microtransactions as well -- when you do that stuff, are you not skimming off revenue as it comes through, or what is the pricing scheme there?

PR: Well even today, we have cross promotion inside OpenFeint 2, even before microtransactions, where if two players meet in a lobby, and they're from different games, then one player clicks on the other player's game, and you go to the App Store and you buy that other player's game? That's what you call our one-touch iPromote product inside of OpenFeint, it's a big draw for a lot of developers, because our community is now three million and growing -- we call it our social bazaar, because the App Store is so cluttered now that it's hard to differentiate. So you use OpenFeint and get your game in front of three million people in these lobbies. That revenue, when someone buys a game using OpenFeint's cross promotion feature, doesn't come from the developer, it comes from Apple. Because we are an Apple affiliate, through BigShare. So we take the user into a webview, which is our own catalog, where you can buy games off the App Store, and then Apple actually pays us. So that's hopefully -- this is the same thing, the whole idea is to get Apple to pay us every time there's a purchase in the App Store, including in-app purchases, as opposed to the outside.

Great. That's pretty much everything I had to ask, was there anything else you wanted to share? I guess we'll keep an eye on the game coming out this summer.

JC: Yeah, I guess the only other thing worth mentioning is that OpenFeint is available now -- it can be downloaded by anyone from our website. It's real.

Cool. Thanks very much.

We told you everything you needed to know back when it was announced. When it got delayed, we were bummed, but only a little, because we knew we'd soon have it in our hands. And now, it's finally here.

55 levels and 40 challenges of some of the most addictive gameplay there has ever been. Controls feature a "precision wheel" on the side of the screen that will let you line up your shot perfectly. All of the Peggle masters and powers in the regular version made it to the iPhone as well. If you've ever played Peggle, you probably already know that at $4.99, this is a steal, and if you've never played Peggle, we can almost assuredly tell you it's more than worth the price (though there is a free trial for the Mac just in case you're not 100% sure).

Peggle for the iPhone is out. Your free time's days are numbered.

I think the whole "Apple buying Twitter" rumor floating around is about as much of a crock as the "Apple buying EA" one. But I give slightly more credence to this conclusion: that, despite the painful experience of Pippin, Apple is once again putting together a game console. Why? Let the evidence from BNET convince you.

First, Apple is picking up game execs and console chip makers left and right. Second is a whole slew of recent patents, for everything from mixing up media and game environments to management of games acquired from a media server. And third, though BNET doesn't actually connect the dots and say it, we will: Apple is sitting on what might be the best library of independent games anywhere, and it's sitting right in front of us in iTunes' App Store.

For years, console makers have depended on the mercy of publishers to keep their hardware going -- they sell the hardware at a loss, and then rely on the software sales and licensing to make it all back up again. But think of what Apple could do here: improve the AppleTV or Mac Mini, throw in some kind of Wii-like interface, and then break the whole thing open in the same way they did with the App Store: let developers in with a really low cost of entry, give them the tools they need to create solid games, and just take a nice cut from all of the tiny transactions flowing back and forth.

BNET claims that the iPhone's interface wouldn't work on a larger console, but why not? All Apple has to do is figure out a way to translate the iPhone's gestures and taps into a console system, and then they can practically run the games natively. Sure, the resolution would be a little low with a straight port, but that's a small problem to fix. Apple already has the makings of a game console with the iPod touch, and while the rumors may still just be rumors, there's never been a better time for them to leverage what they've already got.

Unfortunately, I missed Eliss the first time around, but I won't make the same mistake this time. It's a game designed by a French and Portugese graphic designer named Steph Thirion, and it's sort of an abstract multitouch puzzler -- you can pull and push together differently colored planets all floating around in a sort of space-like environment, with some groovy synth sound effects and music cuts to back up the gameplay. The game got nominated for an IGF award, and for anyone interested in fun puzzlers (not to mention the possibilities of multitouch in gaming), it's a must-see.

I say "the first time around," because it's been on the App Store for a while now, but the game just got updated to version 1.1, and the main tweak is in the difficulty -- there are now 25 levels instead of 20, and the curve has been adjusted to make moving through the stages a little smoother. And the game got a price drop, too -- you can pick it up for a mere $3.00. As I said, definitely worth it to get a little multitouch practice in for what might be the future of gaming.

Massively has a good look at an iPhone app that's a must-have for players of the space-based multiplayer EVE Online -- Capsuleer 2.0 isn't an actual client, but like the desktop app EVEMon, it allows you to monitor and track your EVE pilots from outside the game. It's also got skill queues built in (unlike other MMOs, EVE allows you to have your pilots level even while you're away from the game, so most of the strategy in leveling actually comes in choosing the next skill to work towards), a skill library, more pilot details, and even a mini-RSS feeder, incorporating a few popular blogs from around the EVE blogosphere.

The two developers of the app tell Massively that their biggest issues in developing the app were mostly by way of the limits CCP (the company behind EVE Online) places on what third-party apps can do with their info.. Most of the things they can't do are built into the game itself, and so it makes sense that a certain amount of functionality can't leave the game client (or else people might never log into the game). The app is currently free in the App Store right now, and the devs aim to keep it that way, but just recently added ads to the mix from the game's official magazine to cover server costs and bandwidth.

Finally, they say they're excited about the possibilities with iPhone 3.0 -- notifications are mentioned, and of course it would be cool to get a popup reminder every time a pilot is about to hit a skill. They're also working on a way to provide stats about the ingame Faction Warfare. Sounds cool -- EVE Tracker is still another possibility if you want to follow your EVE progress on the iPhone, but it looks like Capsuleer adds even more innovation to the mix.

Danielle Cassley took one of the strangest paths you might find to game designer -- just out of a computer science degree at Berkeley, she was trying to get a job as a babysitter when she met Peter Relan of the YouWeb Incubator. And rather than have her take care of his kids, he decided instead to put her in an idea farm and see what happened.

Aurora Feint was what happened -- she and Jason Citron, full of ideas, created a game in just ten weeks that took over the App Store out of nowhere in its infancy. The game originally released for free, and while it promised to be an MMO, it started out as a puzzle/RPG game -- people didn't quite understand what it was, but they liked it anyway.

Almost a year later, Aurora Feint has spawned four different versions and even a social platform, and Danielle and Jason are still full of ideas. In this exclusive interview with TUAW, she talks about how Aurora Feint came to be, what she thinks of the App Store so far (and if developers will ever be able to charge the prices they want), and what's next for the Aurora Feint series (they've just released a new version of The Arena called Daemons) and the iPhone platform. Click the link below to read on.

Neil Young (not that Neil Young, the other one), former EA exec and head of ngmoco, fresh from his appearance at the Apple iPhone 3.0 event the other day, showed up on a keynote stage at the Game Developers' Conference in San Francisco to talk about the big, wrapped present that the iPhone and the App Store are to game developers. The platform is "better than the DS, better than the PSP," he said, referring to Nintendo and Sony's handheld gaming devices, because not only is tops in terms of usability (it's "always on, always with you"), and not only is it easier than any other platform to develop for, but the market is gigantic and growing -- unlike Sony and Nintendo's markets, there are no first party titles to compete with.

Which makes a lot of sense (and Young should know -- his company is poised to become one of the platform's early big developers). Other game developers agree, too -- according to a survey at Games Beat 2009, the iPhone has beaten out social networks, web-based content and even consoles as the area that has the most potential for gaming. There's no question at all: the future is extremely bright for gamers on the iPhone.

Zynga has released a new iPhone game called Scramble Live, and while the game itself isn't anything really new -- it's Boggle, basically -- the technology is pretty interesting. They've already got a Facebook version up and running with over a million users, and the new app will let you play against other users, on both the iPhone and Facebook, in real-time. That's a pretty impressive hook -- rather than building up a new social audience, you can just carry away your Facebook friends and play with them while you're on the iPhone.

Unfortunately, there's a catch (isn't there always?) -- the game's iTunes page says the live game is only available over 3G or Wifi, so us first-gen iPhone users are out of luck for that mode. But there's also a solo mode, as well as a "pass and play" version that you can use to play with people around you.

The game's "on sale" at $2.99 until March 9th, when it'll jump back up to $4.99. If you're a fan of the Facebook version and want to try out some cross-platform gameplay, give it a look.

I love massively multiplayer online games, I love my iPhone, and I love Watchmen, the genre-defining graphic novel series of the late '80s (of which, I'll brag, I have a whole set of first edition copies) that's very soon to be the first movie blockbuster of 2009. That's why the news, over at our sister site Massively, that all of my loves were coming together in what's meant to be a Watchmen-branded MMO game for the iPhone made my day.

Watchmen: Justice is Coming will have 3D environments, customizable avatars, and thousands of players interacting in the game at the same time. Massively's got some video from G4 showing off the app, put together by the apparent newcomers Last Legion Games. Unfortunately, while the concept is lofty (they've got a long-term vision for improving the game based on player feedback), the gameplay itself looks like clunky adware -- the kind you might expect from Warner Bros. and the iPhone deals they've come up with so far.

So we're reserving judgment on this one until we can give it a try, and fortunately we won't have to wait long -- the devs say they've lined up the game for release later this week, right along with the movie. That timing doesn't impress us either -- usually, when a game and movie release simultaneously, one's been hurried to make the deadline, and trust us, it usually isn't the movie. It's Watchmen on the iPhone, so it's hit two of three bases with us already. But it'll need to bring a good game, too, if Last Legion is hoping for a home run.

Jason Rohrer gained some nice accolades among the indie gaming scene for his game, Passage, which took the player through a whole pixelated lifetime in just a few minutes in a very powerful and artistic way. Lately, he's turned his attention to the iPhone -- he released Passage on the platform (though it doesn't work quite so well -- you should probably stick to the free desktop version for the full effect), and has now created another iPhone game that's not quite as meaningfully reflective, but is definitely lots of fun.

Primrose is the new title -- it's due out on the App Store any minute now (and will be released for desktops as well), but Rohrer gave TUAW a pre-release look at the game. You can browse through a few screenshots in the gallery below, and our impressions (it's good) are in the second half of the post.

Our friends at Wired recently asked their readers what their favorite iPhone games were, and their list is a pretty darn good overview of some of the best choices for gamers on the App Store. Some of the picks are already well known -- we posted about Trism way, way back, and of course Galcon has been lauded already. And some of the choices are a little wacky -- Cube Runner is cool, but it's not really much more than a tech demo at this point.

Still, there are a few gems you may not have discovered yet -- JellyCar looks like a lot of fun, and Topple did kind of get hidden underneath the shadow of ngmoco's other big release, Rolando. It's worth a try if you haven't played it yet.

It's notable, as well, that all but the top two choices are pretty simple. As fun as these games are, there's definitely a lot more room for some deeper gameplay on the App Store.
