Super Mario Galaxy (Wii) review
one of the best games created on the wii, really fun, challenging in many ways from boss fights to collecting 100 purple coins, and longlasting. For me it took a long time to collect all the stars and the other collectables in the game, and once you have completed it 100% its not over, you can play luigi's storyline (same as mario's but harder) that takes just as long.
