FU: the Freeform Universal RPG is the lightweight, super-flexible, super-fun roleplaying game that puts your characters at the centre of the action. 

The core of FU comes down to this:

• Characters are described with evocative descriptors – no “stats” or other numbers!
• Only players roll dice, letting the Game Master focus on guiding an awesome story
• Conflicts and obstacles are approached with closed questions – “Can I leap the chasm?” “Do I disarm my opponent?”
• The dice answer your question with some combination of YES / NO / AND / BUT which you use to drive the story forward
