This game is extremely impressive on a technical level for a GBA title, it contains a ridiculous amount of cards, lots of AI opponents, puzzles, challenges, etc. I also like how you can pick a structure deck at the beginning instead of being handed a bunch of garbage like in most Yu-Gi-Oh! games.
However, this is still a GBA game so it's rather limited in some aspects. I'm of the opinion that a simulator like this needs a campaign of sorts because otherwise it's better to simply play with other people. Also, the low resolution means most cards look awful.
Old games like this always have some value because they help preserve a time in the game's history, but I would probably recommend a different one for 2006.
