I think I'll play as a Human Barbarian who adventures because he has nothing else to do. His tribe was wiped out years ago, and society certainly doesn't accept him, so he travels with this group of adventurers that he met in a town some time ago.
Of course, if no one else is playing a Barbarian. I usually play either a Sorcerer, Cleric, or Paladin, but the Barbarian was the first type of character that I ever played as in a D&D-like board game, before I ever got caught up in roleplaying games. (the board game was called Hero Quest for any of you that might know of it)
