It's a great game with a lot of strong features. But it has some problems.

Pros:
+ A lot of skills you can use. Many of them are weapon specific.
+ Positioning is important. Arrows fly in straight line, not on curve, so you can block whole line of companions with shield or protect yourself by using environment as a cover.
+ Character progression is satisfactory, even though I would like to manage characters in more ways than just by attaining new skills.
+ Item progression is good. There is a lot of weapons to choose from. The number of armors could be better, but still, it's pretty good. There is a lot of miscellaneous items for de/buffing, blocking the path, traps...
+ Some of the guests are really good. Far better than anything in Skyrim or other "full–fledged RPGs".
+ Your companions have distinct personalities. They are well written.
+ Crafting is pretty robust.
+ Managing the party and camping is nice change of pace.
+ Great soundtrack.
+ Graphics are really good for this type of game.
+ Animations are good.
+ Atmosphere is great. The feeling that life is hard is palpable. You can see that people die because of weather, or nature or by crossing the path of a wrong person.

Cons:
- Some of the skills are useless. You'll be using the same set of few skills most of the time. Patch focused on balance could help.
- Game is trying too hard to show that everything is not black and white. Some quests don't have a good ending. That would be fine, if it was achieved in a logical way. This is unfortunately not the case. Game artificially limits the options to deal with the quests. You can't even abort a quest if you can't role play it properly because of artificial limitations.
- UI is bad. Managing the camp is a chore. Entering an area is a chore - why do you always have to select companions if in most cases they will always be the same? Why aren't they pre-selected? Why aren't they at least ordered right next to each other for easier selection? Why is their order changed randomly? There is a lot of UI problems, which will get on your nerves the more you play it.
- A lot of bugs. Game crashing. Quests which cannot be finished. Characters falling under the terrain. Half of the area inaccessible due to invisible walls, etc. They tried hard, I can tell. First few hours are basically bug free. But they evidently didn't have enough time/resources and majority of the later game is full of bugs.
- There is only four or five different camp maps, and if you'll set out to clear all of the camps, it will get tiresome pretty fast.
