Earlier this week I downloaded Plants vs. Zombies by PopCap Games for the Mac. It's a simple tower defense game that pits lumbering zombies against great varieties of aggressive plants. Your job is to fill your yard with enough plants to keep the zombies from reaching your house.

The first few levels are quite easy. In order to amass your green army, you've got to collect sunlight. Some plants, like sunflowers and certain mushrooms, give off sunlight that you can gather. The rest you collect from the sky (in the daytime, at least). As you complete each level, you're offered another plant.

Many little touches make this game great. Select the help menu and you'll find a "hand written" note that says, "When the zombies show up, just sit there and don't do anything. You win the game when the zombies get in your houze." One zombie variation gets especially angry when you knock his newspaper from his hand while another, dressed in a red leather jacket, white socks and black shoes, summons dancing minions to launch a well choreographed group assault.

Zombies drop coins that you can exchange for additional features, like the number of plants available. Asset management gets harder in later levels as you can only choose a few plants for each assault. Just remember, you always need sun!

Beyond the game itself (there are 50 levels in all) are several mini games, puzzles, survival mode and even a peaceful zen garden. Additionally, you can browse the almanac to see exactly which types of zombies and plants you've encountered as well as what's left. The music and sound effects are fun. I found that it looked jaggy in full screen mode, so keep it in a small window.

Plants Vs. Zombies isn't Eve Online, and it's not meant to be. As a fun distraction during break time or leisure time, it's a great little game. You can play for 60 minutes for free. After that, you'll have to pay $19.95US. It's definitely worth it. If you just can't get enough, check out the extras.

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.

Yesterday we posted about the Apple press release announcing that the SDK had been downloaded more than 100,000 times in four days. It's also worth noting, however, that Apple basically confirmed that several well-known developers are officially supporting the iPhone and bringing some exciting applications to everyone's favorite handheld. In addition to the developers represented on stage at the SDK event, of particular interest are:

• Intuit (of Quicken fame) which wants "to create powerful iPhone applications."
• Namco, specifically mentioning Pac Man and, my favorite, Galaga.
• NetSuite, developer of SuitePhone (CRM software similar to salesforce.com).
  
• PopCap games, working on the extremely addicting Peggle as well as classics Bejeweled and Zuma.
• Six Apart, which is developing an iPhone native TypePad blogging client.

In short, it's obvious that the App Store is going to be chock full 'o goodness once June rolls around. Personally, I'm slightly worried that with Peggle and Galaga on my iPhone I'll never get anything done.

It would seem that I am on a mission to completely derail any chance I have to properly prepare for Macworld. First I decide to perform a brain transplant on my MacBook Pro, and now I find myself playing Peggle like a mad man.

We first covered Peggle last month, when a Mac native version was released by PopCap. Not content to merely suck all your time at your Mac away, the fine folks at PopCap have released Peggle as an iPod game as well. It costs $5.99 on the iTunes Store, but it will cost you much, much more in the way of lost productivity. Even the Wall Street Journal likes this game, though I am not sure when the WSJ started reviewing iPod games.

The full Mac version will cost you $19.99, but that includes lots of rainbows and a talking unicorn so really it is a steal at any price.

Boy, it seems like everyone was waiting for me to write up my gift guide before releasing some interesting Mac games this year. First Horde of Orcs comes out, then Sonic of all things appears on the iPod, and now here's two more fun gaming experiences appearing on the Mac.

First, our sister gaming blog Joystiq reports that PopCap's crack casual game Peggle has appeared for OS X, and just like most of PopCap's games, it's so addictive it should probably be regulated by pharmacologists. It's a universal binary, too, and right now it's only $10 (50% off from a sale on PopCap's site). Be prepared to disappear from your relatives for long stretches of time over the holidays, though-- anyone who can only play one round of this at a time is either not human or just in serious trouble with their spouse.

And MacNN reports that Bomberman has now appeared on iTunes as well. Hudson Software has produced an official port that features an "intuitive control scheme" (that I'd be interested to see), an exclusive boss stage for the iPod, and the option to play the game's music or your own during gameplay. Wild. That game is $5 and available as a download from iTunes.

It's beginning to look a lot like Christmas for Mac gamers-- turns out there may be more underneath the tree than we hoped earlier in the year.

Apple is releasing games for the iPod. EA and id show up at the WWDC keynote. And the rumors say Nintendo may team with Apple for the iPhone. All signs point to an Apple that seriously wants to reenter the gaming market, an arena that has been dominated by PCs and consoles for quite some time. But exactly how can they do it?

They're doing some of the right things already, and we can expect them to do more in the future. But here's five suggestions (or predictions, if you will) about what Apple can do to attract gamers back to the Cult of Mac.

1) Put (even more) games on iTunes. Steam is a nice digital distribution system, and Xbox Live Arcade is a better one. But no one has done digital distribution like Apple has with iTunes-- first music, and now movies and television shows. What they need to do is add games to the software, and even go so far as to create a kind of "iTunes Arcade," where you can buy games for your iPod, your iPhone, your Mac or MacBook, and even your Apple TV. And I'm not talking dinky downloads like Lost-- I'm talking EA's Madden, Need for Speed, and even Battlefield 2142. Run patches and updates through there as well (EA's Link might not like that, but it hasn't been successful enough that they wouldn't consider joining iTunes if asked), use CoverFlow as a cool browsing and launching interface, and you've got the key not only to a solid revenue system, but also a promotion and distribution channel.
