At one point i was playing fallout 3, just loving running like hell and avoiding raiders in the wasteland, and i get stuck between two cars.
Tried fast traveling, would not let me because there were raiders nearby, and they could not loving find me, no matter how much noise i tried to make. Then i decided to load my previous game, but decided against it when i realised my last save was from 2 hours before then, which i had done a lot in those 2 hours. It was loving 30 minutes before each individual raider had finally shown his face and allowed me to blow his head off.
