Mine would prooobably beeeee

1: Zelda
2: Mario
3: Metroid...

Zelda is my fav. Nintendo series period... nothing's ever gonna beat it out... well, unless they make some new and better series or it starts sucking :p

And then mario... well, I never actually bought Mario 64, but I played it a lot at my friend's house and it was good fun... And recently with all these mario topics and me playing Super Mario World on my friend's SNES, I've been looking forward to it more than I was before...

As for metroid... still looks good... but I'm not a big fan of the series... :D

As am I...:D
