Quests for Pathfinder: Kingmaker are covered on this page.
Pathfinder: Kingmaker will feature plenty of storyline and side quests, for a total of 80 hours per playthrough (estimated). Your character will be a baron and then a royal ruler, but the way you interact with the world in the quests will impact how the game and the storyline develops. There are multiple endings planned, affected by your choices, companions, and alignment.
While the game will be true to the Adventure Path, it will not be a rote recreation of it. Expect Owlcat modifications, like in any proper PNP campaign.
