Angry Birds Space looks like a total rip off of this neat flash game where you put a golf ball through a ring located on a distant planet while taking into account the mass of the bodies in space. http://www.kongregate.com/games/FunkyPear/gravitee?acomplete...
Angry Birds itself was a rip-off of Crush The Castle. Just having the game design doesn't sell; you have to find the right dressing. If I was the Crush The Castle guys, I'd be crying into my corn flakes every morning.
one was stolen from another, agreed. but you have to admit to "replace" warriors with crazy looking animals and do it as a major project of a games company needs some balls involved. And it worked out. For that reason and the difference in anything else than "crushing elements" between those two games, I dont think they cry in their cereals.
