@owashii@snouts.online If I recall it's the same Dragon Engine that Y4+ (so, 6, 0 and 1K) use. But they altered some of the gameplay mechanics becuase... well they're kinda tied to what was in the original Y2 on PS2 a little. They've done a heck of a lot extra tho to bring it more in line with the newer experiences (4-6 + 0 )from what I've recalled.
