NSMB doesn't count because it has no creative overworlds (filled with fancy effects, but no creativity like the ones in SMB3 have).
Isn't that kind of up to us? Also, if the thread's gonna be called "Favorite Overworld", could it include all overworlds?
I'll go with the Desert themed overworlds. I think they're some of the most challenging ones and they rock.
