Consider this:Mario 64, in space on Wii. Sound good?
Story:It's always a mystery how Bowser always ends up taking Peach, and runing away with Mario close behind. This time he blasted of into deep space and was going to build an empire at the center of the universe. Mario follows him, but passes out and ends up in a obseritory and is told to collect power stars so that he can fly to the center of the universe and save Peach.
Gameplay: Overall somehow, against all science, this game does not get repetitive. In each level you know in your mind that your doing the same thing over and over again, but every level practicly feels like a differnt game. The game runs, feels, and has almost the same controls as the original Super Mario 64. You have a place where you can blast off to different galexys that have about 4 stars each. To beat the game you must collect all the stars.
Graphics:The cartoon like looking graphics look great.
Replay value:Wii games are expensive, but it's worth it. I like to play my favorte stars over again. My persinal favorate is one it a toy land as you disarm a giant robot.
Conclusion: Die hard Mario fans should get this game, or platformer lovers, or people own a Wii should own this game.
