We've been playing Warhammer recently, which has some interesting critical hit tables.


True story:
Our group has been assisting an outlying village with its problems but the head of the town guards was rather offended when one of the PCs was talking to his girlfriend ad challanged him to a duel.

It was a short and bloody fight, the Pc critted and the head guard collapsed, the part healer patched him up but he'll be awhile recovering from his injuries.

The party headed out of town to investigate some other issues and ended up in a cave, after clearing the cave of bad things (during which the PC who fought the duel was badly injured) we were challenged at the cave exit to come out un-armed with our hands up... which obviously didn't happen.

Some members of the party ran out of the cave and initiated melee, the PC who fought the duel stayed back and used his crossbow.

The enemy were also split into melee and archers and responded in kind, the melee fighting our melee and the archers shooting our crossbowman.
He was hit, in the leg, a 1 point critical (minor injury) the roll on the critical table was made and it was quite serious, the PC was out for the combat and his movement would be severely impeded for some weeks to come.
he was shot in the knee by an arrow and would have to (temporarily) retire from adventuring, but there was good news as the local town guards have a vacancy...
