Who sets the goal of the campaign?One is the goal of the campaign, and the other is oppositional to the point of obviation of the premise. You don't start with the goal, you work toward it.
In Burning Wheel, there is no "the goal of the campaign". There are goals of the PCs, and these are set by the players, riffing off one another and off the GM in the set-up phase and then as play unfolds.
