OP, I love your post and would just like to do a quick tribute. This question from simulating Witcher 2 choices...
... was never asked to me. And yes, I said I was on Roche's path. I'm actually sad I wasn't asked it.
By the way, how many kings are alive in the north at the start of The Witcher 3? Only the king of Novigrad and the emperor of Nilfgaard (who invaded from the south) or are there more? (Spoiler mark if necessary; no details necessary). I remember at least two kings from The Witcher 2 who could be alive at the end of that game, but I'm confused as to whether they are still active now. Not sure if Skellige has a king also.
