Yeah, I traded in some of my crappy GCN games, memory cards, and controllers(I only kept one of each[except the games]) and got NSMB. ;D The gameplay is sweet, and it's pretty challenging. The control system is very easy to get used to, since you only use the A/B and X/Y buttons and the control pad(and the touch screen...
). Plus, the graphics are top-notch for a platform SMB(you can see some pixels, but they backgrounds are amazing too). The music may seem repetitive, but it only plays 1 song every other level or something.
I don't want to spoil anything, but if you want to know about it, either PM me and I'll tell you about the game, or check GameFAQS, IGN, or other gaming sites...
Here's my sum-up:
Controls: 9/10
Graphics: 8/10
Music: 7/10, since it uses sounds from SM64DS(which IMO isn't very "New").
Gameplay: 10/10
TOTAL: 8.5
