| Our group just started using this system. We need to gain some experience with it and I need to gain some experience in running the challenges and coming up with good partial victory and failure results, but I think so far that everyone likes it. 'Course, they had complete success each of the two times so that probably helps.
It really helps create a good story, especially, I think, when you change the primary Skill and the described conditions and situation with each segment as time moves forward.
I'm inclined to raise all the DCs by one not because I necessarily want to increase the failure rate but because I am inclined to say "Yes" to a player even if their rationale is pretty thin for using a Skill that they're good at so I want to front-load the difficulty a bit.
Thought I'd post the two challenges we did. It took me only a few minutes to create each of them and only a few minutes to explain to the other players how the system works. I was very impressed with this aspect. I'm looking forward to creating some challenges in-game with only a minute delay.
