The PC casualties in that campaign were ridiculously high. Just getting from the beginning to the end of the session with the same PC was an exhilarating victory. That's why I'm all for save-or-die, level drain, zero level funnels and balanced-dungeons-my-ass. Not because I'm enjoy forcing players to suffer the same way I did, but because I want them to experience the high of just escaping the session with your life.
