Purchased this game when i purchased the Wii unit as it came with an extra remote as well. I immediately played bowling and absolutely fell in love with it! It is a fantastic family game, and my whole family loved it. We did end up playing for some time!
Baseball is another good game, however there are only three innings and you can't control the catching or running of your players.
My son (13) loved tennis and can't stop playing it, which is good as he breaks a sweat when playing and loves it.
Golf is also a family favorite, and you will find yourself playing for well over an hour.
There is also a test which will give you your "wii fit age". It isn't as extensive as the Wii fit unit test, but it is good. The other games are also entertaining, but Bowling hands down is the best.
