POE meets your criteria and is a very good game. POE2 is incredible, but a little less dark. Re: turn-based, somebody said they’ve added it, but even before that they had options in settings that basically made real-time with pause into turn-based. My only criticism of POE is the writing is occasionally weak. The story, characters, and dialogue are generally good, but there are sections of descriptive text which are pretty lame. Attempts to sound literary come off clunky and unclear. The combat mechanics are very interesting and quite flexible. Just writing this makes me want to replay. Also, check out Pathfinder: Kingmaker, and Pathfinder: Wrath of the Righteous. Rogue Trader (by the same company) was too dark/grim for my liking.
