Yes. Yes it is. Excellent story so far. Gameplay is the best of DnD mixed with the best part of Divinity Original Sin 2. Difficulty is maybe a bit harsh the first few levels when an encounter with a bad initiative can take you out before its your turn. It looks graphically good and runs fine on older graphic cards. The companions have interesting backstories and related quests.
I havent tested it in co-op yet.
I have encountered a few bugs: Actors missing in cutscenes. Money-stacks getting corrupted. The ugly pre-order clothes just disappearing after a patch. But nothing serious.
