Here is my gift to the world: an idea. NPC: The Game, stars you, but as an NPC, who has to walk around and say the same thing over and over again. You also jump out around corners, only to be cut down by much more powerful player character. You get sick of this kind of treatment, and decide to do your best to make the PC's life a living hell. The drive of the game would be parody of the major genres.
