Neat Idea

(if something like this doesn't already exist)

Someone should create a game, or a gaming machine sort of thing, that has around 50 or so seperate games in it, and when you get it you start on game 1, and to continue onto the next game you have to beat the previous one, but each game gets harder and harder as you go along

It would be an interesting challenge and you could get all kinds of different challenging game genre's in there
