Play Yu-Gi-Oh! Duel Monsters 7 : Kettou Toshi Densetsu Online
You get thrown into a grimy city where every duelist’s out for blood—scrounge for cards, build a deck that survives, and pray you don’t run into some guy with three Blue-Eyes on turn two.

Yu-Gi-Oh! Duel Monsters 7 on the GBA is one of those weird, chaotic spin-offs that somehow works. Instead of a linear story, you're dumped into this lawless city where you duel random opponents to climb the ranks—no hand-holding, just raw card battles. The pixel art for the monsters is surprisingly crisp, and the deck-building actually makes you think, especially when you stumble into a duel against some overpowered NPC with a stacked deck.
What I love is how unpredictable it feels. One minute you're crushing some rookie, the next you're sweating bullets against a guy who somehow has three Blue-Eyes on turn two. The rogue-like structure means you're always scavenging for better cards between fights, and losing stings way more than in the mainline games. It's got that janky early 2000s Yu-Gi-Oh! energy, complete with hilariously broken combos if you know where to look. Just expect to reset a lot when RNG screws you over.
