This is probably the best LEGAL Yu-Gi-Oh! Simulator to date. Older versions like "Legacy of the Duelist" pandered to anime fans too much or had shitty graphics/music. Master duel makes up for that by having much better graphics, UI, and music. Additionally, plenty of card archetype lore quests to finish give you plenty of points to spend in the shop. Admittedly, the game feels pay-to-win with the high points required to get good cards from a pack, maybe, but that applies to TCG & OCG as well. Pick this game up if you want to play this specific format with the UI and don't care for fan-made projects. It's free!
