"Communication between the Game Master and the players is crucial to keeping the game fun. Solicit feedback from your players from time to time and see how they feel about the experience. If they curse, spit, or stab you with a pencil, it means they probably arenโt happy with the direction the game is going. Sadly, there isnโt much you can do about this, unless you want to give them their way. And honestly, whatโs the fun in being the GM if youโre just going to let players have their way?
UPDATE: Ah. So THATโS where the โrocks fallโ joke originated!" ~Shamus
