So far, several high-profile games have been released in the new Mac App Store (solely for some games). This includes Bioshock, Modern Warfare, Borderlands, and more. What shouldn't be forgotten is that the Mac App Store exists on computers such as the 11 inch MacBook Air. What this basically means is that you now have the ability to play REAL console games, on an extremely portable device, that's a Mac! Not to mention the fact that several of the games released are seeing their first visit to the Mac as a platform. Basically, you now have the ability to most conveniently shatter splicers in Bioshock or shoot your friends' heads off in MW... all on a device as portable and as light as the MacBook Air.
