Graphics: This is the part where the game really falters. A point that makes this game slightly better than the others is that the AI 'cheats' significantly less, leading to a richer gaming experience.
The game follows the rules of the actual card game, requiring you to basically knock out your opponents life points before they knock out yours. It plays the exact same way as the other games, so if you've played those before, the learning curve isn't exactly steep. Gameplay: In this game, you are a duelist who's sole purpose is to beat a slew of other duelists, which are, of course, spawned from the TV and manga series. As far as renting or buying, I would suggest renting, unless of course you're a huge Yu-Gi-Oh fan, in which case I don't even need to tell you to buy it.
This game is perfect for Xbox Live, and it's therefore a real letdown that this feature wasn't included.
Overall: This game could have been a lot better than it was, had it not been rushed.
