Yesterday evening I was looking at the code and I think there could be an easy way to keep both Roxy and Natalie paths open. Since this AVN is coded in a rather linear style and all events are blocked by simple decision logic, I believe that if you manage to open the console and write natalie_event_12 = 0, then the last event with Natalie is considered as it never happened.Is the Natalie scene in the last update only visible for people who follow the Roxy path?
If so, does that mean that there's a way to avoid the Roxy path at all? Never thought about doing that XD
Of course you might stumble on some weird dialogues every now and then, such as Roxy being happy once she learns you're screwing her sister or Natalie not caring you're still with Roxy while she "trains" you.
