Will keep you entertained for a long, LONG time.
The random amount of fun in this game is what makes this game hilarious. Note: This game's story mode is short short SHORT and beatable in 2 hours tops, so don't expect a sort of deep comedic tale, just mini stories that are so random that it's a suprise Wario makes an apperarence. The microgames are so much fun and insane that you'll really break a sweat if you play for a long amount of time.
Before each microgame, a different position is given to hold the remote, followed by a flash of direction such as "Insert!". There is no way of even attempting to avoid doing the positions because there is no time to think of an alternative way to, let's say, hula-hoop or dance. That's the beauty of it, you're stuck embarassing yourself and doing ridiculous poses in order to keep up with the constant flow of insanity.
Anyone who has a disability, steer clear of this game. Sorry to say, there is no way to avoid the more physical microgames without getting creative, which may cost you the game. Then again, I don't think many disabled people own Wii's, no offense to anyone.
Short storyline aside, this is a magnificent and entertaining way to show off what the Wii is capable of. FUTURE WII GAME DEVELOPERS SHOULD TAKE A LOOK.
