Sounds good to me. Though open world games have their place I'm glad they're back with a focused game and a full experience from the get go. No planned DLC's is just chefs kiss - idk why this is even a thing in modern titles.
The party members having their own ai is fine.. I really dislike micromanaging team skills in most action game as it slows down the experience. Maybe on the fly combat orders will be there; like act aggressively or defensively and certain abilities like summons are user based.
