yay 242 / 242.
I liked playing as Luigi better, the game seems to be a little bit more difficult with his varied abilities. Cosmic Luigi also is crazy, and makes the race challenges actually worthwhile.
You must of played the hell out of this game to go through it a second time, I've only got 71 stars but I think I might play through it a second time as Luigi if I still need something to do after I get the first 120 stars..
