This is the first game Mario and Sonic are in together and its really fun, but it gets old kind of fast.
The Olympic sports are all depicted as mini-games where you compete against the computer or up to 4 other players. Each sport makes great use of the Wii remote. The controls for the most part are great except for some events like archery. Some other events include running, swimming, fencing, and table tennis. The game also has special dream events as well. This game is great at giving you a workout as well, especially if you play the running events.
More events can be unlocked as you progress through the circuits. You can also unlock trophies and emblems which can keep you busy for a long time if you want to collect them all.
The best part about this game is the multi-player mode. Its just a lot of fun to play against some of your friends and family. This is a game that everyone can enjoy. If you don't have enough nuchucks, don't worry, most events can be played with just the wii remote, and if the nuchuck is required, the players take turns using it.
The graphics are above average and the sound is nice. Every character looks detailed and is animated nicely.
The only thing that I dislike about this game is how fast it gets old, especially if you are playing it by yourself. This is a game that I can not play for hours at a time, its better to play it for a short amount of time every once in awhile.
Overall, I think that if you are looking for a fun party game you can play with other people you should consider this game. The controls are great, the graphics are good, and the game is fun.
