I have no idea what some people's idea of "much better" looks like.
This is a dungeon crawler... literally Dungeon Travelers with NTR H.
Given the art we've seen from Leane 1 & 2, I doubt we would get a whole slew of new H asset or other major changes.
This is an open world with no time limit, so you have room to explore and figure things out. There is also a new game+ for when you know what you are doing. Dev is doing a great job fixing bugs and doing QoL like letting maps carry over to NG+. So no, it's nothing like a cybertrash release.
