Eternal Duelist Soul is a good option if you want to experience what YGO was like during it's earliest inception. There being no banned cards & instead having a few very powerful cards be just limited to 1 makes this game pretty funny to look at with a modern perspective of the game.
The game is slow (but that's more due to the nature of early YGO being slow) & the in-game progression feels needlessly tedious requiring you to defeat different duelists from the anime multiple times in a row to progress to the next set of duelists where you just repeat what you did before.
