I recently released OpenArena on the mac appstore, in case anyone of you wants to try it. It's an arcade styled FPS like quake3 or unreal tournament. I'll be adding content to it soon. With the removal of PPC emulation, this game is the only id tech 3 arcade game right now that runs natively on Snow Leoprd and Lion. http://itunes.apple.com/us/app/open-arena/id422263923?mt=12 Happy fraggin!
