There's also the "negative reinforcement", which I think has at least two aspects to it:If you play BW a different way, you are literally doing it wrong according to what the rulebook lays out as the procedures you are supposed to use when playing BW. I think the rulebook even states that not following the procedures in the rulebook means you are playing it wrong. It has a "positive reinforcement" approach to help incentivize the players as there is a very specific form of XP that can be earned, but only by overcoming challenges tied to a PCs goals. Said XP is integral to how certain aspects of PC advancement works so missing out on gaining said XP is a big deal.
(1) For the player, if you don't earn artha - which requires play that engages your Beliefs, Instincts and Traits in the relevant ways - then you can't really have any hope of success;
(2) For the GM, if the players don't have goals that inform (i) scene-framing, and (ii) intent-and-task resolution, then you can't really do your job.
