I feel there is alot of replayability for seeing more content, but without an ending that resolves anything and with so much of the content being arbitrary RNG. There is alot of replayability but the dearth of resolutions and certainty that difference choices will actually lead to experiencing the different consequences in companion dialogue, wains desire to replay it despite the replayability? does that make sense?
I had a vague notion when I started reloading saves to see what the other outcomes for certain story beats would look like and there's really not much there. Replaying the game reveals how little replayability there actually is. Your choice effectively boils down to "Do I want to do a quest the right way or the evil way?"
There are a few exceptions where you get to see events from a new angle
(like doing the Nightsong quest with Balthazar)
but it's very sparse and usually punishes you in some way.
