Graphics: 4/5 Pretty decent. Most of the game looks pretty cartoony, but when you get to the minigames that feature Gamecube games, the graphics look very nice. It really is pretty hard to rate the graphics, though, given that the game has a very random artsy feel.
Sound: 4/5 Not much to be heard. Yeah there is a little music and a few seconds of sound during the gameplay, but the cut scenes are just annoying and can't be skipped, and the sound has nothing spectacular.
Control: 4.5/5 WW:SM has some very unique controls perfect for the Wii. There are different positions you hold the Wii remote to do certain mini games, and the game tells you before each one. Also, on the final stage of the game, you can use the nunchuk. Pretty nice control, although not perfect.
Fun: 4.25/5 Warioware: Smooth Moves is a good game, just not the best game. It gets repetetive if you play it a long while non-stop, but in short bursts, it's great. There are also unlockable mini games that are also pretty fun. Warioware: Smooth Moves may not be the best game on the Wii, but it certainly is one of the better ones.
