I play this video game on my Gameboy Advanced regularly. To me, it is a card game like poker only better. Yu-Gi-oh was very popular back about a decade and everyone was collecting cards. What I enjoy most about it is the strategy that is necessary to win, building a solid deck and the vast number of cards to choose from. This game was created towards the beginning of the anime and has only the classic cards, but in my opinion, it the best of all the Yu-Gi-oh Gameboy games I've played.
I rate the graphics a 8 because though you don't get to see the graphics of the monsters summoned like in the anime, but the cards are replicated nicely and you do see what is going on on the field as you play, like when a monster is summoned you see the little tornado to indicate the summon. The visual is very clear and easy to understand.
The sound gets an 8. I like how the sound effects are accurate and clear throughout the game. There's sound for everything that happens in game play so if things are moving a bit fast visually, you will be able to get what is happening by sound. I also enjoy the music. Somehow the music is relaxing and winds me down.
As for addictiveness, I rate 9. If you really enjoy card games and/or if you like the Yu-Gi-oh anime, you will likely play this game over and over again. For me it has become a habit.
This game gets a 7 for story because it is mainly working towards obtaining all cards. After you win all the tournaments and obtain all the cards there is really no more story in the game.
I rate the depth a 7 because though it takes a while to win all the cards and build a strong deck, after you do, the fun is mostly gone and you want to start over again.
The difficulty of this game is around 7 because unless you cheat and turn off the game or reset when you are about to lose, you will lose a lot. Many of the duelists are pretty tough after the first group until you can strengthen up your deck.
Overall, I rate this game an 8 because it is addictive, fun, and takes a little mind power but not too much so I find it unwinding (as long as I don't keep losing

).
