Lame.
Super Mario World has already been discussed to death, both positively and negatively, so this can't possibly be any more interesting than any one of the other games on the poll. I doubt I'll be playing the game, though I might still join in on the discussion (which will likely be copy/paste of things I've said on other forums).
I think it's probably the weirdest Mario game (even more than SMB2 USA).
I couldn't disagree with that more. Super Mario World might have a few oddities here and there but it still features the same conventions and enemies as all other main Mario games released before and after it. Super Mario Brothers 2 is a battle for Mario's subconscious, it doesn't have Bowser in it whatsoever, Peach and Toad are playable characters, and the enemies include masked shy soldiers, flying masks, walking bombs, egg-spitting transsexual dinosaurs, mobile cacti, inflated ego mice, etc.
