Mario Galaxy for the Wii? I'm finally on the part where I have to complete all the purple comets (trust me, it was after much sweat and some tears LOL). If you ever need tips, give me a shout.
Did you know you can play the whole thing again as Luigi after collecting all 120 stars as Mario?
Also, when you have collected all 120 stars as Luigi, there's a bonus star! yay. LOL
