Creator VS Character Identity

[Samven]

I like to be one extreme or the other. Either give me a blank slate I can build up and establish on my own (ie: Commander Shepard) or give me someone who's already got a fully-fledged personality so that I can see it develop further (ie: Luke fon Fabre). I'm not a massive fan of the wishy-washy, "Put your name in this lead character but he doesn't do much because he's a silent hero who is actually not important to the plot" stuff.
