Chewbaccus, Mario Kart was one of my favorite "social" video games! I can't wait for Mario Kart Double Dash to come to GC. Fighting games, racing games and multiplayer shooting games are the best for social gaming. My girlfriend and I tend to like playing platformers together though. We just beat Harry Potter together and next we're going to play I-Ninja. Have you seen this one? It looks really fun-->
