>>9910946I really wish Dungeon Dice Monsters had caught on, because I loved the idea of having actual collectible Yu-gi-oh monsters. But holy shit the US release was cheap garbage compared to what Japan got.
There's also Capsule Monsters, a gachapon game they played early on in the manga, which I'm now realizing was likely inspired by Neclos Fortress. Pity the actual tabletop game they made out of it had none of the charm since it was just Duel Monsters characters again.
