Dude. I also did basically everything, but with a new char I can check how different stuff plays out with different choices in different order of completion. Permutations are a thing. Stuff has widely different outcomes.
And smaller things like: If I unpetrify the Drow Royal before the Spectator does and mind control her, will she have something interesting to say? Will I gain favor with her house? Will she tell me a secret?
Stuff like that. Or try doing dialogue encounters with the origin characters - they get unique choices.
