There are approximately 2,225 applications available in the Mac App Store, according to Distimo, and 646 (29 percent) of those programs are games.

"The popularity of games in the Mac App Store combined with the fact that there are already 646 games in the store, signals the Mac App Store could boost Mac gaming," Distimo notes.

Windows has traditionally been the preferred platform for PC gamers.

Games aren't just for the Mac, however, and are the most popular application category across all three Apple stores, Distimo found. Productivity apps such as iWork and Bento take second place in the Mac App Store, while entertainment apps such as SlingPlayer Mobile or Sketchbook Pro are the second-most popular type of apps for both iOS devices.
