Aaaaaaaaaaaaaaaaaaaaanyway, back to the actual topic.
So it seems the successor to one of the most mediocre Mario games ever failed to impress? Color me shocked. I'd rather play SM3DL than this carp. Yes, I said carp.
If anyone's going to bother spending actual money on a NSMB game, then they should wait for the Wii-U version. The A-Team is working on that particular title, whereas the unpaid interns handled the DS game.
I absolutely hate the NSMB graphic style and music, but NSMBU is SIGNIFICANTLY better looking than the prior games in the series, both because it's in HD (with no awful jaggies thank GOD) and a much improved art style. It looks 50-60 percent like a brand new game, almost.
