I know there are a lot of 'Which Character Are You?' quizzes around, but I think this one's pretty good, and offers decently reasoned results.

I ended up as Vincent (the result pic is in my sig). Most of it seems accurate, if a little exagerrated in places. It's always encouraging when one of your favourite characters matches you. I wouldn't have minded coming up as Reno either, bits of the justification ring true.
