Dogs in the Vineyard (DitV) is a tabletop RPG masterpiece. Set in a semi-fictional setting based on pre-statehood Utah, you play a religious enforcer for the [Mormon] church. You ride from town to town rooting out sin and delivering justice.
More importantly, DitV has wonderful conflict resolution mechanics, based on the idea that every roll of the dice should be a critical plot point, and that everything else should just flow along. The system encourages you to care about why you're struggling and constantly ramps up the tension by asking how far you're willing to go to achieve your goals.
I have to say that this is the first truly narrative-centric game that clicked for me and my roleplaying group. We've all had tons of fun with it, and it currently ranks perhaps second in popularity to Call of Cthulhu. It's independent and awesome, so it'll make a great choice for a Tabletop Tuesday. (The My Life with Master post was my motivation for suggesting this, since those are our two biggest Narrative success to date. Damn, I've really got to run Sorcerer and Trollbabe soon....)
BTW, if you'd like, I can write this. It'd need a little time, but ask and I'll get it done.
