You finish all the levels, get all the stars, then get 9999 star thingies that you can fire. Then go to the very last place on world S and finish that.

It is super Mario 64, Super Mario galaxy, and Super Mario galaxy 2.
super Mario galaxy 2
Yes, You can play as Luigi in Super Mario Galaxy 1 & 2. In Super Mario Galaxy 1, however, you need to really want him. He'll only be playable after collecting 120 stars with Mario (Double what's needed to beat the game).
I think you can because if you can get her on Super Mario Galaxy 1 than you can get her on Super Mario Galaxy 2. Hope this helped :)
Super Mario Galaxy 2 is only for the Nintendo Wii.
Super Mario galaxy 2 does not have a cheats system.
