Take: http://armorgames.com/play/12409/one-and-one-story Mercilessly rip it off: http://itunes.apple.com/us/app/id482595165?mt=8&ign-mpt=uo=4 Profit. This is a lot worse than just cloning a game, it's even ripping the media. Don't understand why it's done or how they can get away with it. An idea is still worthless though, as it's not proven. But take a game like that, which is an IGF finalist and you have a proven concept worth copying.
