So as of yesterday, Paizo has now released for the first time an adventure path which tries to re-instate player pro-activity and also tune down some of the assumed meta-plot and rail-roadiness in their flagship product. The AP is called 'Kingmaker', and is touted by Paizo as a hybrid between a campaign-with-plot and a sandbox: players have to scout the wilderlands to the south of civilized lands, tame the wilds, establish a new barony, and fight off any forces that assault their new kingdom. In short, it's the players whose characters set in motion their plan, and the DM is their to throw adversary forces at them to foil these plans. In short, a beautiful return to the Expert set for Basic D&D/BECMI.
