I thoroughly enjoyed this game but felt the story was weaker in comparison to the first Pillars of Eternity. I will say that the most massive improvement in this game was the multiclass system as it allowed me to theorycraft which I have always found personally enjoyable. They also added a ship minigame which is tolerable imo but not the reason I enjoy this game.
Also the party limit in this one is reduced by one, so max party limit of 5 in game companions or ones you've created at the taverns. As for the two main dlcs, I enjoyed Beasts of Winter but felt that seeker, slayer, survivor was kind of a slog to get through.
I'd still recommend this game if you're into party based isometric games though. Also there are to modes of playing turn-based and the regular stop and pause mechanic with the spacebar.
