When i said "another GGGB" i meant it in the sense of how lewd the content would get. In other words no, i don't think the game is going to get as silly as the late-GGGB BBC gangbang parties, bimbo porn star career and mind control drug-fueled rape. That's how i interpret the author's words about keeping things more grounded, that's the reason to assume this kind of content won't turn up in ORS, and why i'm saying your prediction is ignoring the words of the author in favor of what you personally want to see.
But's that based entirely on your interpretation of what Eva has said, and not what she's actually said. You can't say for certain that you're right and I'm wrong, until Eva says so herself. Until that happens anything is possible.
Lena is already making her own porn content, so it's not much of a stretch to imagine that she might eventually do mainstream porn. She probably won't copy Ashley and become a stereotypical bimbo, but I don't see anything to suggest that there won't be some kind of porn career for her, later in the game.
And there may not be a BBC gangbang, but a gangbang of some description seems entirely plausible, if Lena has previously stated she want's a threesome with two guys. Once she's done that, is it so hard to imagine, she may end up doing it with three guys as Ashley did?
And as far as drugs are concerned, well she's already started using Molly, and on the last occasion it required 'Will' NOT to use it, which suggests a certain amount of dependency is developing. That says to me clearly, further down the road it could become a real problem for her, just like it did for Ashley. And a drug dependant Lena could be willing to do a lot more, than she currently is, and end up getting into bad situations.
