"iDevGames, the leading website for Macintosh game developers, established the uDevGame Contest in 2001 to energize game development on the Apple Macintosh platform, encourage innovation in Mac games, and to recognize the best Mac independent game developers. Since then we have received 60 entries and given away over $19,000 worth of prizes."http://www.idevgames.com/content/contest.php?id=10
