NSMB DS was a nice little game, i've beat it 3 times and counting and i imagaine it will be a mainstay in my DS rotation, but the greatest mario game ever it is not. It really feels more like a reimagaining of the first super mario bros to me, like hey if we'd had the tech and experance 20 plus years ago THIS is what we would have made.
OT: SMW FTW, this game still looks just as good as it did when i was 12, and i still drag out the snes to rock it every now and again.
