It's one of the best RPGs there are. The choices actually matter a lot. I'm really sad there's no part two and now online algorithms are reminding me of it so I want you to know of it too!
Can testify to just how good the story is. I've only completed a single store line but the game is rather short (about 30-40 hours for a slow first play through I think?) encouraging you to go through repeatedly to find all the different story progression possibilities. Like OP said choice REALLY matters in this game and can have consequences sometimes altering the entire path of the story unlike most games where the storylines usually "converge" back to a singular plotline.
The combat is comparable to Pillars of Eternity and there is an interesting magic rune system, but it's story is where it shines, each faction and storyline is fully fleshed out with interesting conversations, companions, and lore. Additionally unique questlines, companions, locations, and more are accessible or change according on your choices. It's worth at least 1 playthrough but there is enough for about 5 or so playthroughs through the various branches.
