This has to be the most fun I've ever had with a multiplayer game ever.
It costs 20 bucks on Gamecube and it comes with Pacman World 2 in a bundle. You need one of those gameboy hookup things and a gameboy advanced. The person with the gameboy is pacman, and watches the gameboy screen, and the other people watch the tv and try to get pacman. And it switches around and junk. It's really fun. It's worth it too.
Buy it.
