I gotta say I am very impressed with this game. I am not a turn-based, team-based RPG guy (for the most part, I did enjoy the two recent Xcoms & Wasteland 3) so I was apprehensive. It took me until maybe 6-8 hours to truly understand the combat, which I basically thought was just move + melee/arrow/spell, and I struggled a TON in battles because of this. Understanding the environmental options, throwing items, and (accidentally) stumbling onto how stealth can/does work has made the combat really satisfying. Still a challenge (I play on the medium setting), but feels incredibly fair.
I also wanted to say that I am still in Act I and have 27 hours recorded in the game. Some of that is me being a completionist, some of it is that I struggled in a few areas and replayed them a ton, and a lot of it is that I got (I think) near the end of one of the two branching paths than turned around and just started the other. I thought I was ready to transition of of Act I with about 12-14 hours in the game, then learned that those travel areas are actually full blown areas with a ton to do, not just a quick travel transition.
What a ride. Anyone that has considered this game but was concerned with the turn-based combat, take a chance at it. I created a human fighter as my character and its a straight-forward role to help learn the ropes. I wouldnt' suggest starting with a pre-created character until a second play through.
Last note: every NPC having a unique name & some dialogue wasn't something I thought I would care about when I started, but damn if it doesn't increase immersion a ton. Even the little 'filler' NPCs are named & can make comments on things you might have done that impacted them/their area/their group.
