GM long enough, while playing by the rules, and eventually it's going to happen. The dice are going to come down wrong, or the PCs are going to make the world's worst decision (trust me they will), and you are going to end up killing the whole party. So what now? What do you do?
Some of us look kind of fatigued and just don't know what to do. Some of us get up and do a happy dance of victory. Some do a happy dance of victory in jest. My question for you then is this: How do you deal with the TPK?
For me it depends on the situation. If the players went into it knowing full well what they were getting into, I generally give them a "good try" or "nice game" and go from there. If the dice just screwed them, I try and make sure that it was the dice and not me. On a few occasions, the players have had to tell me I didn't do it.
How about you?
