A lot of big picture work has already been done on Pathfinder Online, and it's going to be a bit different from your traditional fantasy MMO. It's going to focus around the characters you create, in a world that will grow out of your interactions, developing the way you choose to develop it. It takes place in the River Kingdoms of Golarion, with our own Kingmaker Adventure Path providing some of the inspiration. There will be an overarching storyline, and dungeons aplenty to explore, but where Pathfinder Online is going to thrive is in the ability of each of you to leave your mark on the world.
