Yu-Gi-Oh Eternal Duelist Soul

Contrary to popular belief, I do play a handheld game on occasion.

As a kid I was a pretty big Yu-Gi-Oh fan. Watched a lot of the anime, and played the card games. Cousins used to beat my ass every time we played. I was introduced to this game through them, and added it to my GBA collection. It's still something I put in and play even to this day. If you're not a fan of the card game it can get boring real quick as it's basically just playing the card game against characters from the show. I managed to unlock everyone to my knowledge. Yami Bakura is the hardest opponent in the whole game IMO.
