Super Mario Bros. 2 was my favorite of them all actually. I liked how the game looked and played. It's much more cartoonish. All of the bosses are fun, and as Double-J pointed out, it had great monsters like the Shy Guy, as well as the Snifits and the Bob-ombs. I think I'm going to have to hook up my SNES and play it again (I have it on the Super Mario All-Stars version).

I never knew it was another game originally, "Doki Doki Panic". That really explains why the games is so different.
