I have rarely played any kind of RPG but I read the posts here out of curiosity.
Background
A GM has spent weeks or months designing a game world. Well into the game a character invents a nuclear bomb and kills everyone. Of course this is an exaggeration but I think you know what I mean. Basically it spoils the fun and wastes a lot of work by the GM
Question
How commonly does someone spoil a game like this and what is the usual response?
Examples
- Give up in despair
- Sack the player
- Start up again just before the disaster
- Both of 2 and 3
- Something else
- Persuade the other players/characters to gang up on the miscreant and slay them in game before they can carry out their dastardly plan.
EDIT - ADDED to list but I hope not invalidating any answers, is the following. 6. Persuade the other players/characters to gang up on the miscreant and slay them in game before they can carry out their dastardly plan.
Note: I did my best with the tag. Please add any that are helpful.
