Mario and Sonic at the Olympics was one of the most anticipated games released on the Wii in 2007, but it was also the most dissapointing. A lack of detailed gameplay, repetitive mini-games, and buggy controls are enough to ruin what could have been an excellent game.
In the game itself you are able to play from over 20 different events from ping pong to gymnastics. The games themselves can hold your attention, but get stale quickly. On the positive side, the graphics are very crisp and some of the best to come out for the Wii for far. The cooperation from Sega has given the game some classic characters such as Sonic and Dr. Robotnic, something that hasn't been done in ages.
Overall the game is decent, but it is a major missed oppertunity. If you are looking for an expansion on Wii Sports you will have to keep waiting because this doesn't come anywhere close.
