Is this one worth playing over the original?
I played the old one and now I play this one, so I don't have to chose.
But I think it's worth giving it a try (otherwise I would not be here, there are enough crybabies around already). The new scenes with the girls are done well, also the new gameplay mechanics are fit in good - except in one case, but the ingame hints should help with that. Some very bad story arcs are done better here, the whole Olivia thing has been changed drastically, also the development between the characters makes more sense.
