I recently finished the early access content (chapter 1).
I really enjoy the game. It has a nice, in-depth D&D-based combat system, with plenty of environmental effects and factors.
You run a 4-man party, although if you have more NPCs then they can still join your party and just wait at your camp.
The storyline itself is a bit odd and dark, and I don't love it, but the rest of the game is great.
