Epic's most profitable game is Infinity Blade for iOS

And here's why we're going to continue seeing AAA games makers getting involved in Apple's iOS platform: Epic Games reports that Infinity Blade, which has earned over $30 million in the past 18 months, is by far the company's most profitable title, "in terms of man-years invested versus revenue." Epic has some much bigger titles than the iOS (and Android) hack-and-slash game, including the uber popular console hit series Gears of War. But those games take much longer to produce, so in terms of time invested versus money gained, Infinity Blade is a much more profitable title.

Now, that doesn't mean that every AAA studio out there can immediately switch from making console hits to freemium iOS titles -- not only is Infinity Blade a high quality game, but it benefits from Epic's reputation and ownership of the Unreal Engine, as well as unprecedented promotional support from Apple. But it's clear that there's a huge market in iOS, especially for AAA game developers with the experience and knowhow to make great games.
