Great fun for hardcore gamers and the whole family
First sport, Tennis. Wii sports tennis measures up to hundreds of different movements on how you swing the wii remote. It tends to get pretty boring if you are playing alone but it measures for a great party game. Next up, Baseball. Baseball is a heck of fun while your on your own or with another player. Player 1 bats while player 2 pitches while the CPUs are the fielders. The AI is pretty polished, for example if you hit the ball really high they may drop it from time to time. But it fails in some ways when they are always where the ball is and when you see one on one side of the field there at the other side of the field in a second. There is three innings in a game, it sounds long, but its just right.
Bowling. The perfect party game. Fun for everyone. Even single player. But 4 players is the most fun. The remote acts as your arm with the ball in it and a simple bring the remote down and back up flick of the wrist works perfectly while your system's miis watch you. Sweet.
Golf = Boring. Nice control but its not my thing
Boxing is awesome and its 1-2 players and you use the wii remote as your right hand and the nunchuk as your left hand (you can reverse that option in the game). Its awesome on your own or with another player.
Finally, the Wii Fitness Test. The game takes you through 3 different tests. There is hitting home runs which gives you 10 opportunites to hit home runs. The second test is picking up spares in bowling, which is pretty addictive and the final test is hitting 50 balls in tennis into the court rather than outside. After all these tests, the game will calculate your Wii Fitness Age and send the results to the Wii MessageBoard. Of Course, after it calculates it will show your Wii Fitness age on the spot. 20 is the best possible score.
Overall, Wii Sports is fun for everyone that comes with every Wii system, and its great fun even if you dont like sports.
