Well, there have been several good ones, but the one of which I have the fondest memories playing is Cressa, my monk of Tyche in the AD&D game my friend George ran for us in college. I'd never played AD&D before (and only a couple sessions of OD&D) so this was something new. And the rules I was running, Chivalry & Sorcery, were totally western medieval and so there weren't any oriental style monk/martial artists. Also, most significantly, this was my first ever female character. I can't remember now why I decided on female. It probably just felt right for the character. Nobody in the group had a problem with it and the game was hugely fun (thanks, George!). I still remember our final big battle with the evil anti-paladin. We were winning when suddenly he leaped onto his winged anti-paladin mount and took off over the castle walls. Only Cressa had a ranged weapon to bring him down--but the javelin just missed and he escaped. A fantastic cliff-hanger moment ending that episode.
