I just didn't really like how they've left out characters or replaced them with others. The book universe was so much better, to me.
I must confess I have not played either, but I have been wanting to try for a while now. What would you be interested in playing? Following the book storyline or something else? I think the more we talk about it, the easier it will be for me to decide whether I'd like to try Stefan or Damon. Right now I am leaning a little more towards Damon, but that isn't set in stone.
