Re: Magical traps (spoilers)
 

Yes. I applied Rule Zero a lot during the Gen Con runs because I could've written 20,000,000 words of rules and still not had anything for what my players wanted to do. ;)

This explains why, despite my insanely tight space restrictions in the game, I found room for Roll and Shout! (Exploits, p. 12), the lengthy intro to Running the Game (Exploits, p. 86), and Settling Rules Questions (Exploits, p. 91).
