how do you all feel about using a deus ex machina? i'm not sure i like the idea myself and i've never seen it used in a game where it didn't elicit suppressed groans from the players. i wonder if you think it would ever be appropriate? any one ever use it or been in a game where it was used to good effect? i'm thinking specifically about divine intervention here, but i'd be interested in hearing about any sort of improbable instant solution used in a game.
