I like how cinematographic the game feels, particularly the conversations. The plot is great. I also like the combat in general, i.e. the animations, the implementation of rules (even though it could be improved by being more true to 5e), being turn-based, etc. And I love the enemies that you have to face, the hag is particularly amazing. And finally, I really like the freedom of exploration and the design of all areas, especially the Underdark.
