Wii Sports overall is a solid sports game that contributes to the Wii's controls very well.
The graphics are good. They are cartoonish rather than the real-life look, since you play with your Miis. The framerate is actually pretty good in the game, since it doesn't seem to lag much. The graphics aren't eye-sores.
The audio isn't bad, though can get annoying at times. The chimes can get repetitive at times. The sound effects of the game are superb though.
Wii Sports gives you tons of replayability since it is an arcade game. It is probably the best sports game out yet. The game is still very fun for me up to date, so it isn't bad to play.
