What was the quickest that a PnP game went south for you...
So, a group of us decided to play Warhammer a few decades back (shyut yer mouth youngin!) and one of my friends decided to play a rogue.
There was another player with my namesake that this rogue could not stand...he was playing a dwarf berzerker or some such.
The DM begins the game, us all starting in a tavern. Within the first MINUTE, the rogue decides to pick the berzerker's pocket (because he didn't like him in RL) and promptly gets caught.
There goes the rogues hand. There goes our rogue. And the game devolved into several petty arguments.
We never picked that one back up or even really played that night.
To this day, I GUARANTEE if the rogue and berzerker met again in RL....they would argue about that incident.
(My ranger slunk off into the shadows and abandoned hope of finding a party at that tavern:P)
