The squeal to Super Mario Galaxy.

Super Mario Galaxy 2 is MUCH better than the first because they added Yoshi (yay) and Yoshi power-ups. There's a "Fat Albert ass load" of really awesome/challenging levels/bonuses. (The first game was hardly challenging at all.)

For everyone who pwned Bowser in Super Mario Galaxy 1 and thinks they do it in Super Mario Galaxy 2... Bowser is harder, so expect to lose a few lives. The final galaxy (Bowser's Galaxy Generator) is a great challenge, too.

HINTS: 1--Secret Mushroom: When you start Bowser's Galaxy Generator, you will see a path that goes to the left. Climb up the pole at the end of the path and you will see a the red mushroom with the yellow star. (Increases your life to 6.)
2--Super Ground Pound: Jump, spin, and while spinning, do a ground pound.

The new mario game (as of may 2010) which is a sequel to the original Super Mario Galaxy. It adds a LOT of new content, and old content returns. For more information, why don't you go on a mario fanboy's site and read a wiki on it yourself.

if you don't plan on getting this game, i recomend suicide. i got mario galaxy 1 earlier this year, and beat the game in 4 days. i've almost got all the power stars, however mario galaxy 2 offers much more of a challenge. so please, fucking do the world a favor and get the game!

The act of getting really fucking pissed off and breaking your dad's $1500 dollar 42 inch 1080p TV after failing a level for the 9001st time.
