Video game icon Mario launches into space and encounters a multitude of crazy creatures on unbelievable planets. Players master the changing gravities they encounter while exploring each planet and collecting Power Stars. For the first time, Super Mario Galaxy lets a second player lend a hand in "co-star" mode. Using the revolutionary motion-sensitive Wii Remote, the co-star can point at the screen to collect starbits to shoot at enemies, deflect incoming attacks or stall enemies to help Mario. It's a way for the newcomers that Nintendo has brought into the world of video games to play right alongside their more experienced peers.

"Super Mario Galaxy is a game that everybody can play, whether you've been a Mario fan for 25 years or you just started playing Wii Sports," says George Harrison, Nintendo of America's senior vice president of marketing and corporate communications. "It's an easy favorite for game of the year and should stand as one of the best -- and most beautiful -- games of all time."

In the game, Bowser crashes the star festival and carries Princess Peach's castle into space. On a curious new planet, Mario learns a powerful spin move that players pull off by shaking the Wii Remote. Mario also has an arsenal of new transformations at his disposal, including the Boo Mario, which causes him to float and fly through walls, and Bee Mario, which turns him into a beyond-adorable flying bee.

Super Mario Galaxy is Rated E for Everyone.
