Looks like the Wii version with effects turned up to high. Nothing really wrong with that I guess, the original has great character models.
Also NMH is one of my favorite games this gen, and I put it on equal grounds with Mario Galaxy, despite the latter being FAR more polished. I will be the first in line to shout out the many, many things wrong with the game, but the story, art direction, characters and gameplay mechanics clicked with me. It didn't with MadWorld, which I found extremely boring. Simple as that.
