I'm kinda disappointed that they didn't add more references to SMB2 in 3D World...well then again the game hasn't come out yet so who knows there might be more that we haven't seen, but yah love this music. Now that I think about it, this game was kind of a strategy game, I mean you've got four different characters with different abilities/stats each, where each can excel at certain levels. Like there are some levels were it's easier, or maybe only possible to beat by using Peach, or Luigi, etc.
