The characters don't move as realistically as hoped, though. When you hear them talking, their mouths don't move. Plus, they usually have the same expression on all the time, and, to be truthful, it does get repetitive. The N64 can do better than this. It has been proven,but,we must keep in mind that graphics aren't the most important part of a game, and they don't make the game, either.
Graphics are still important, though.
Anyway, aside from the disappointing expressions, all the other parts of the body move when they dance around in victory, or collapse in shame. The sound in Mario Party isn't bad at all. Whenever a certain person or thing talks, they have their own sound. When you meet Bowser, he growls. When you meet Toad, he yells happily.
