A good question!  And yes, this game redefines the limits of narrative control.<br/><br/>First of all, just because you have Privilege doesn't mean you can just walk all over the other guy.  You get to say whether or not you succeed or fail.  That's it.<br/><br/>But...<br/>For each die that you've wagered, you can add<em>another</em>fact, beyond simple success or failure.<br/>The loser gets half his wagered dice, if any, and alternates with you in adding details.<br/>And no wager can directly contradict a fact already set.<br/><br/>Yes, this means that you can really shaft someone else.  It also means that you can be shafted in turn...<br/><br/>By the way, some people will have Blessings that might allow them to cancel out all of your wagers, so all you get to say is whether you succeed or fail.<br/><br/>Have a look at the Player chapter in the core book, which is all about just such issues, and contains some lovely suggestions that I'm going to start using in my tabletop games as well.   >:)
