Gnometown Hero
It works out fine. I ran a con game doing this -- deciding in the moment to just roll with the crazy stuff the chaos monsters who showed up wanted to do -- and it was a blast.Just a thought experiment:
What if for a new campaign or just a one shot, the GM said "Yes" to literally everything the players asked or wanted to do. Not "Yes, but," but just "yes, you can do/be/use that."
Normally, the GM hedges, using die rolls or negotiation to craft play and control pacing, and sometimes to maintain a level of control over the world and the characters. What would a game look like where the GM gave up even a hint of control and just narrated the results of the PCs' choices and successful actions?
I don't think it will be comfortable for all personalities, though.
