Gamecube has the best 4 player party games... Monkey Ball, Monkey Ball 2, Super Smash Melee, Mario Kart DD, F-Zero, Wario Ware, Zelda: 4 Swords, FF: CC... none of those do you need to be "mature" to play, you can just have some great, genuine, unique fun with 3 best friends and get more excitement going than any same-old-same-old FPS multiplayer.
