Collect all 120 stars and then talk to Rosalina. She will send you to Bowser's Galaxy Reactor. Defeat Bowser, and you will unlock the option to play the game again as Luigi.
Repeat this process with Luigi to unlock the final galaxy for Mario and Luigi.
Basically, you get all 120 Stars with Mario. After that, Luigi becomes playable once you beat the final level while you have the 120 Stars.
There are two Luigi's and the second one gets you the Luigi stars. The second Luigi mentions that the Luigi you're playing as looks like him, and that the universe is big enough for something like that to happen. Rosalina also refers to the second Luigi as the playable Luigi's twin instead of brother. Also, as Luigi, the letters from Peach (although still addressed to Mario; The Mail Toad makes note of this) contain ten lives instead of just five. The playable Luigi is noticeably shorter than the Luigi that gets the hidden stars, and obviously jumps higher than Mario. He also has less traction (he slides farther when you stop), and his costumes change to match his green color.
If you are trying to find the new galaxy that is born after you beat the game with 120 stars from both Mario and Luigi, it is located among the group of galaxies unlocked by green stars, next to the Terrace.
Believe me, it's an awesome game either way.
You must collect all of the stars with Mario and defeat bowser and essentially defeat the whole game with Mario, then you get to be luigi.
To be Luigi you have to get all 120 Stars with Mario.Then you can play as Luigi, only when you get 121 with Luigi you can get 121 with Mario.(Luigi 121 first -Mario 121 second)
get all 120 stars with Mario then go beat the final bowser again. after the credits, a message saying you can now play as luigi will pop up. select that same file from the main menu and there will be a button where you can switch from Mario to luigi.

After betting a mission by playing as luigi a luigi ghost appear, and it does different think depending on the mission, and galaxy that you play as Luigi in. ghost Luigi shows where 1-up are located, he show where comet medal are, he show how to get the hidden star.

Beat the game with mario, by getting all 120 stars and by saving peach twice.
Beat Bowser in world 6. After the credits and some other stuff you unlock luigi. But first check your mail toad.
Super Luigi Galaxy isn't a real game but in both Super Mario Galaxy and Super Mario Galaxy 2 you can unlock Luigi and play him.
Yes, Luigi is playable in Super Mario Galaxy. You unlock him after getting all 120 stars as Mario.
The Characters starred in Super Mario Galaxy 2, are the same in Super Mario: Mario Luigi, Peach, Toad, and the other character that will star in the game, Yoshi.

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).
"Super Luigi Galaxy" is not a game you can buy at the store. But, you can buy Super Mario Galaxy and unlock Luigi. To unlock Luigi on Super Mario Galaxy, you need to get all 120 stars. Then, you can play Super Mario Galaxy as Luigi.
No, there is no such game as "Super Luigi Galaxy," period. That's just a nickname for when you play Super Mario Galaxy, for the Wii, as Luigi.
(The hey is wrong with you?) No, you cannot kill Luigi in Super Mario galaxy. (He's too precious)
once you have completed the game as Mario and beaten bowser at least twice go on the menu then press the switch that has the Mario and luigi heads on it and you will become LUIGI
Wario is not in mario galaxy 2 but luigi is.
No you can't play as Princess Daisy in Super Mario Galaxy, but you can play as Rosalina & Luigi.
