World building is fantastic.
Story feels really FRESH.
Characters feel more believable that most RPGS.
Dialogues feel very well made.
You choices do matter.
5e implementations work well. Good job Larian.

-
Classes lack identity. For example - all classes can use scrolls.
Surfaces rule, they are the true pantheon of this universe. All hail the surface lords.
UI too close to DOS2.
Lack of backround for your own character (this will probably be adressed).
Enemies shooting through doors, but you can't (just a bug, will be fixed).
Unable to choose which character handles interactions with NPCs. Not that great when many interactions are forced upon you.
