Playing D&D is a social experience. It’s often as much about getting together with your friends as it is about killing monsters. But I’ve noticed that we spend a lot of time talking about stuff that isn’t even related to the game. This has really become a big problem in public-play games at my FLGS. I’ve noticed that over the past few sessions of D&D Encounters I’ve had to ask people (with alarming frequency) to stop talking when it’s not their turn and pay attention to what the other players are doing, and that got me thinking: what if you weren’t allowed to talk during an encounter or an entire gaming session? How would things change?
To begin this kind of gaming experiment, the DM must make it clear to the players right from the outset that anything they say, anything at all, even if it’s something that their characters obviously wouldn’t say, is going to count as an utterance by their PC. Absolutely everything the player says his character says. No exceptions. Silence is going to be the key to success. Excessive noise will either force the PCs to fight something they know they have no chance of defeating (hence all the sneaking around) or it will lead to a final confrontation that is a lot more difficult because the PCs kept talking. In either scenario, the stakes should be incredibly high.
