What do I think? Well, Super Mario Bros: The Lost Levels has no business even being on the list as it's just a rom hack created by Satan. I won't argue Super Mario Galaxy ranking higher and Super Mario Galaxy 2 as I'm in the camp that actually likes the original over it's sequel. I don't think it's the best Super Mario game, though. I'd save that honor for Super Mario Bros. 3.
The Mario Kart series is hands-down the best spin-off. Luigi as the better Mario brother? I agree and will always argue in Luigi's defense. The Hammer Suit is awesome and it better be in New Super Mario Bros. 2. I loved Rosalina and thought she was a great addition to the Mario universe. I actually enjoyed the bits of story we got from her in Super Mario Galaxy, which added more to the story than simply saving Peach. Heck, her inclusion in the game made me actually care about the story in a Mario platformer.
Anyway, those are my thoughts. What about you?
