Mario & Sonic at the Olypmpic Games is a very good game. The wi-fi capabilities are outstanding. You can be running in a race on your own and upload your own records to the world. Some of the normal events (not wi-fi) are: 100 meter dash, 4�100 meter freestyle, and the javelin throw. These are just some of the many fun games. You start out by making a profile which takes a few minutes. Then you can go race. You can play with up to 4 players. The gameplay is very nice and something to keep people occupied for a long time. This game is awesome and I recommend it to everyone.
