I saw 2 commercials for "Super Mario World 2," then never heard about it again.  That was weird, considering how much hype there was over "Super Mario World" and "Super Mario Bros. 3."  I remember calling up Blockbuster to see if they had "Super Mario World 2" to rent, and nobody on staff knew it existed.  Why was it advertised so little?  I know it's a pretty lousy game, but did it bomb that bad?
