It's a pretty simple idea on the surface. Inspired by Houses of the Blooded and Inspectres (mostly HotB since that's what I've been reading), what would happen if you turned the pass/fail of a skill roll into win/lose narrative control. A success means the player can establish a fact. If the roll was to Intimidate a shop owner, then the player could say one fact the shop keeper told him, or something else entirely like "I get there to find his dead body, still warm."
Completing a skill challenge still has the same rules. 3 failures and it's over, or getting the necessary successes to beat it.
Now, there are some potential tweaks. Like not having the DC scale up, but letting players take a -5 for additional wagers (power to state additional facts). Providing "style" points for establishing facts that add complications, make things harder, or are just plain cool. But I'm mainly curious if anyone sees potential pitfalls that I'm missing in the basic idea of turning D&Ds success/fail into narrative control as far as skill rolls, and especially skill challenges go.
