I played a yugioh game on my GBA, but I honestly can't remember why or how I got access to it.
I played a couple duels and it was fun, but I couldn't ever win, and then I have no clue what happened because I never saw the game again.
I'm not sure if the game was ever technically mine, or if I was borrowing it from some random person or what, but it's sorta a mystery and my memory of all of that is surprisingly hazy.
