Wii sports is the best. I loved all of the games (except boxing) and even got my mother into it, good for family and solo play. Gets you off the couch and moving (a little). This brings out the wii's full potential. Definitely rent this.
Ok so this game came with the wii, and at first I didnt give it much though cuz i had went out and bought mario kart and mario galaxy. Well after a bit I finally played it and was quite surprised. The bowling is just plain out fun, tennis is really good, and the golf...well lets just say that if golf on tiger woods was this fun and easy to get the hang of it might not be collecting dust on my shelf. I didnt really like the boxing or the baseball, but hey, for a game that came with the system it was pretty good.
