I doubt I'll play any of them much...if there's some sort of intro story for each then I'd play that, but I prefer to RP my own character.
Seems I'm not alone in this...perhaps there's an opportunity here for Larian to publish a collection of short stories featuring the characters, ending up on the day the flying squid attacked Baldur's Gate?

(In fairness, if there was a dwarf amongst the selection, I'd be a bit more inclined to play that, but there isn't.)
