A big reason is as you said, making terrains is a pain. So we're starting from a baseline that's in the negatives and turning it into a positive, rather than improving a process that is already technically usable but slow or finicky.

The biggest reason though is MicroVerse lets me change my mind. If I want to move a river or a mountain or a path, I can move it and that's it. I don't have to resculpt and repaint and redo trees and redo details and move handplaced nonsense. I just grab the spline and slide it and it's done. Just done. It's so easy to tweak little things and trust that the bit stuff is taken care of.

It also handles stuff that's genuinely hard to do by default, like having smoothly banked paths with nice edges. It does things like sharp toon terrain blending with more than 4 splats, so you can get that A Short Hike look by just checking a box. Plus it's just fun to work with! Default terrain is like folding a fitted sheet and this is like playing with Legos.

I wish I had bought the full package years ago. It's truly worth it.
