The strong side of this game is that there are so many different characters. Do you want all to be the same? I don't. And I find Jenny one of the best. She does change a lot, just read her diary.
Some girls are bitchy at first and stay that way, some are bitchy and become soft, and some are soft from the beginning. I hope for one that is soft at first and becomes more confident (if not bitchy) later on -- maybe Judith would be such a candidate. It all depens on how the story is being told and DC has not yet disappointed me.
