isn't like those gimmick games that require four GBAs


It's not a gimmick. It also requires 2-4 players when GBAs are involved, so odds are you can find enough friends for them. The one I own is the Zelda one, and as far as co-op games are concerned, it is one of the best I have ever played. The only problem I have is finding a good schedule to get people togther to play the game. But the use of a second private screen is an interesting and fun innovation.

LAN based multiplayer is becoming more and more common on consoles, and wasn't started by Nintendo. Halo was the big one that started this, since XBox live wasn't launched yet. Mario Kart is still 4 player on one console using split screen.
