I'm halfway done with 1440%ing mario galaxy 1

if you dont know what im talking about
basically there are 6 game files you can play on in smg. to 100% the main game, you have to collect every star, which is 120
when you do this, you unlock luigi. you can grab another 120 on the same file. this makes 240.
240 on every file. rhats what ive been doing
ive basically mastered the game

"wow! you 100% mario galaxy...3 times!"

must...play! must , get stars! MUST WIN!
