Such a amazing game from a amazing company.
Gameplay:
To start it out, Super Mario Galaxy has amazing graphics to start with. It's just too perfect for any other Wii game. The controls don't take very long to learn until you know how to play this game. Also you can change into different forms like Bee Mario, Boo Mario, Fire Mario, ect. These forms may come in handy for getting the stars. So i'll give this a 10/10.
Story:
The story starts with every 100 years the shooting stars rain over the Mushroom Kingdom. So they celebrate with a Star Festival. Mario comes to the Festival to meet with Peach, that is, until Bowser breaks the festival. He takes up Peach's Castle with a UFO beam (wait a minute, taking up Princess Peach's castle? This sounds like Paper Mario all over again). Mario managed to get on the bridge trying to save the princess until a Magikoopa appears and shotos Mario off the castle. With the Luma saving him, he takes him to this planet where 3 other Luma live. After catching them, he then heads to the big mama, which introduces her as Rosalina, protector of the cosmos. It is Mario's job to collect the power stars and defeat Bowser to save the universe. not bad except for the bringing Peach's castle up in the space with makes it sound like Paper Mario. 9/10
Music/Sound
Music on this game sounds pretty good. Just like all the Mario type games. The sounds have changed during Super Mario Sunshine. Overall this gets a 9/10
Replay Value
Replay Value is high. After beating the game, you can collect all the stars and unlock another character to use to collect the other stars. 10/10
Overall
38/40
This games lives up to it's hype. Probably the 2007 game of the year for the Wii. You must buy this game if your a Mario Fan. If you can't get it yet, rent it and try it out. You'll like it.
