So, I've been spending most of the last days on that game. My feelings on it so far :
-I like the worldbuilding. It looks pretty solid, none of the nations or gods are terribly cliché. The books are also a nice way to get more in-depth about the lore. Although some of the things are quite obviously a reskinned D&D monster.
-Characters are interesting enough, I guess, but I feel they don't interact enough, or have enough dialogue. (Tyranny did that better, iirc)
-Class/character building system is alright. Although some of it is weird (raising Might on a caster type to get more spell/ability damage ? What ? How is Might both psychic strength and mental strength ? Just make those depend on Resolve or something) and it's so obviously inspired by D&D that it should just have kept the D&D system. The spells are just plain out of a D&D manual, but they "repainted" them. Why not use the original spells and not confuse people ?
-The game is quite dark. Sometimes it tries too hard to be edgy, but it's usually quite reasonable about that. It's like a weird mix of Baldur's Gate, Frankenstein and Berserk. Which I appreciate.
-Difficulty is terribly schizophrenic. (I am playing on Normal, started on Hard then went at Normal) On the very start of the game it's quite easy, although don't get into that bear cave. Then the difficulty ramps up exponentially if you don't get a tank (kiting those trolls with a cipher and wizard...), and as you get more party members it becomes normal or even easy. And then... some enemies are an afterthought, more speedbumps than anything else, and some are BS, and you're not sure which ones are. (Well, mostly druids with Call Lightning, the undead/fair folk that spam Maggot Infestation or Insect Swarm...). Again, I am playing on normal and I feel most fights are too easy, but considering the difficulty who's all other the place, I think I'd just wipe next time I find a difficulty spike if I go to Hard mode.
-I like the large amount of quests, they seem quite well written for the most part. Dialogue is good.
-I dislike the backer content. It breaks my immersion (golden NPC names, same approach), it could have been included better, it isn't interactive, it doesn't reward you other than just reading stories, and it seems like Mary Sue and bad writing bait. I just stopped looking at them after looking at a few. Now I'm sure there are some that are well-written and worth reading, but there are just so much of them... And I don't know which ones are worth reading. Well, it's just a way to get money from the backers.
-I like the reputation system a lot. I play a Honest/Stoic/Rational Golden Pact Knight Paladin, and I enjoyed that trial where you could convince others with your reputation for honesty.
-There are some bugs with doors and interaction with doors, also, the pathfinding is somewhat poor. Also ally AI is very lacking, Tyranny did it much better. (I am playing v1.03)
In general I really like the game, despite it's flaws. It's a worthy successor to Baldur's Gate II, and while I like Tyranny quite a bit, I seem to prefer this one. It doesn't reach BG2's/Torment's level of greatness, of course, but then what does ?
