I think I'd have to go with SMW
That funny. I love smb3 and smw. My girlfriend and I beat them both doing every thing loved them. And SMB 2 and yoshis island.
Then we tried Mario 64 when it came out. So boring we quit. Hated the design, the repetitiveness, the movement, the sound, Mario as well.
That was the end of Mario as far as we were concerned.
I find it strange to this day that it is so well liked.
