Sonic Adventure DX could use some work. It's to hard, to many glitches, and not the best graphics. Also, the only fun character to play with is Sonic. However, the beginning levels are fun, and when you actually figure out a level it's quite entertaining. This is one of those games that doesn't appeal to me a ton, but like I said, once you figure out how to beat a level, you can have a lot of fun. Overall, I'd say it's a good game, but not as good as you can expect from a Gamecube game.
