On YJ, four Sengoku Aces have closed at 18,000-26,500. Meanwhile three Blades have gone 20,505-30,000.there seems to be a lot of bootlegs of Aces that go for cheap but it took me AGES to find an original one for a reasonable price
Honestly, I'm surprised Ace goes for around the same price as Blade. For the longest time Ace was a 100 euro game.
