A fun little twist to the standard Yu-Gi-Oh! formula at the time. It takes some getting used to but it's a lot of fun once you do. I can't consider this game mastered because the only two cards I'm missing are only available through the Destiny Draw mechanic and I have too much pride to suck that much ass just to put them in my library.

Definitely went through phases as a kid where I played this obsessively and had to get all my monsters to 9999 ATK/DEF points, for some reason. It can be kinda hard and it's also basically impossible to get every card in the game.
