I said this before. Mario Kart Wii will have a chat room. A lot of gamers are going to use Mario Kart matches as a proxy into meeting online gamers.
Mario Kart Wii has been scheduled for an April 24th release date. The game was moved from May/June back to it's original release date. Game magazine reviewers(The few that already got the game early) gave the game a 8-9/10 range. I'm probably getting it as soon as it comes out. See you guys there.
