If there was any doubt that game development companies were serious about Apple’s iOS platform, the announcement by mobile game developer Gameloft that it has sold more than 20 million games on the App Store should blow away any such doubts. According to the company, of the 47 iPhone and iPad games that they launched from the beginning of this year, an amazing 42 of them have hit the top five spot on Apple’s Top Grossing charts, and 25 have even hit the top spot. After 20 million paid downloads, the company isn’t planning to stop anytime soon and is already planning to release another 15 games on the store this year, including: Assassin’s Creed: Altaïr’s Chronicles HD, Dungeon Hunter 2, Star Battalion and Modern Combat 2: Black Pegasus.
