I'm a relatively new GM, with a relatively new group, they're great guys, but they have so much trouble staying focused. I tested a new system I thought up, but I dont know quite how ethical it is, or if it makes me a bad GM. The basis is, when they are faced with a decision I put a timer on, if they do not answer in that time, an event occurs. Last night we had a group of hostile NPCs that where trying to beat the door of a house down. If the pc's did not decide what to do about them in the given time, they would have breached the door. Is this wrong?
