I think it would be cool to have a game with a number of interacting characters where the player can manipulate the environment, but not control a character. This would have actual AI-based characters playing each other, as opposed to a builder type game.
Since I know this descripion was terrible, lets put it like this: It would be an animation, but the characters would have an AI, not just be scripted. You could do things like tip over flower pots, essentially manipulating events of the world that are possible, instead of how a character acts. Anyone know what I'm talking about/know of a project/want to make it?
