Back when 3.0 first came out I had a couple campaigns going, and in one there was an evil wizard who wanted to take out the party. It charmed a hydra, slipped a ring of regeneration on its toe, and sent it after the party as they were down for the night. They killed it, moved camp (who wants to sleep next to the corpse of a hydra?) and bedded down. The hydra regenerated, and the wizard sent it at them again. They killed it again, burned the body, took the ring, and moved camp again. The wizard raised the hydra as a zombie and sent it at them a third time, just before dawn. They managed to kill it... just. And revive the party members who dropped in the fight.
That was so much fun...
30) OBSCURE RPG you've played
I played a home brew Highlander RPG based on the Vampire system. I think that's the best I've got.
31) FAVOURITE RPG of all time
