I enjoyed the storyline a lot. The gradual reveal of the main character's backstory was nicely done, and I liked the villains. I also appreciate a plot that has a sense of urgency while still giving you "breaks" to walk around, explore, gather some loot. Not sure about the expansions, though. There is a remote area that was originally only accessible through an expansion. With minimal spoilers, it puts your semi-urgent plot on hold for at least two weeks, which seems excessive. Then there is the much more recent expansion which bridges the gap to the sequel - a gap I would have rather let remain a gap. Overall, though, a great game. I got way too into figuring out the rules and looking up how a Fighter/Cleric compares to a regular Fighter and such. :)
Amazing characters! If you're into D&D mechanics, that's a plus, and if you aren't, you can still play it for the great characters! Likeable, nuanced, well crafted, and amazingly animated and voice acted. Astarion in particular is a joy to listen to. And without wanting to spoil too much, I recommend taking Wyll into your party and doing his quest, but don't take his word for what is really happening. Oh, and beware of watching the character intros if you don't want spoilers. A game with a progression, but quite a bit of freedom besides. Many ways to take the story for the different characters, besides the overarching plot. A huge number of small worldbuilding details. A number of nice nods to the original Baldur's Gate series, most of which work quite well. My one complaint is that it feels a little crowded at times. In particular, you can only have a four-person team at a time, out of up to maybe 10 characters possible, and the rest will stay "at camp", but still frequently talk like they are making an active contribution. Besides modding, you can only avoid that by recruiting a smaller team, but that might lead to sadder endings for that character. And also, some changes from D&D work better than others. Whatever.
