From what I've played of the early access, it's a pretty amazing game. It's a lot like the Divinity: OS games, or handles similar to Dragon Age: Origins or Shadowrun. It has a lot of flexibility in how you handle encounters and situations, and the combat is challenging but fun and rewarding. The dialogue is top tier, and rewards paying attention to what's going on in the world around you.

Much like D&D, anytime you attempt something with a reasonable chance of failure the game rolls for you, and your skills or the things you've said/done affect the rolls with modifiers. There's a lot of exploration across unique locales with a lot of verticality to the environments, and a lot of secrets tucked away. All the side quests play back into the main quest in a satisfying way, and it almost never feels like you're wasting your time doing something.
