Mario 3 and Mario 64 are my favorites (couldn’t stand 4-63), with 3D World in third place.
I could never really get into Mario World, and I’m not sure why. I don’t dislike it, I’ve just always felt like it’s a step back from 3, but then again I didn’t grow up on it but played a ton of Mario 3 on All-Stars. Better looking than World, too.
