I, too, have started considering the “run each session like a one shot” thing. I’m even going so far as to scene-jump even though we didn’t finish the previous session, fictionally. Didn’t kill the wraith and find his bones last time? That’s cool. Cut to the building burning down as they stand over his open grave with rusty shovels.
I’m running DW, though and have yet to make some Fronts. Sell it to me – what is it that makes them worth it?
