World: I can't recall if I ever did everything in this game. My gut tells me no. I've beaten it at least twice, but I never owned it.

64: Gotten 120 stars several times and seen Yoshi. This was my favourite game for a looooong time after it was out.

Sunshine: I actually can't even be completely sure that I've beaten it at all, let alone 100% it.

Galaxy: Got 120 stars, but never actually played through with Luigi.

Galaxy 2: Never played.

What about the SMB series? How can you leave SMB3 out of this, you monster? I'll have you know SMB3 is the greatest videogame ever made.
