Wii Sports Comes packaged with the Wii. And this was a smart move by NIntendo as it shows off the Wii's Unique control scheme well.
There are 5 games included in Wii Sports, all of which with fun multi-player. Tennis plays well, although sometimes it would be nice to be able to control the characters. Baseball is o.k, but it hurts that you don't field, that is done by the computer. Bowling Plays the best. Boxing is good, when it works. The doesn't always read your punches. Golfing is another game that is good when it works, as the game doesn't always read the speed of the Wii Remote well. In addition to these games, there is a daily fitness test that tells you your physical age, simillar to the Brain Age series. You can also do these tests outside of the fitness test. All with multi-player too. The game has a simple, yet effective graphic style that uses Miis and good music.
In conclusion, Wii Sports is a good game.
