Yeah, the real issue really is development time. If L&P were to release two full PD's per year, we'd be much deeper into the story, pretty much every route would see progression and Sophia could be at a point of corruption where she's having sex with other characters. 2+, or at current pace even 3+ years of development for a single PD is what makes the story not progress, and so to many the slow corruption based story appears to be even slower than what it actually is.
Sophia having sex with her own son was totally out of question storywise. L&P has been speedrunning the progress in PD13 if we compare it with PD12 or earlier PD's. I personally don't want it to become even more unrealistic as it already is, seeing how the entirety of PD13 was sexual encounter after sexual encounter. One PD is basically 12-16hrs San Alejo time. So in my opinion, what we've seen in this update and the PD in general is a huge leap considering Sophia's current corruption and constant pangs of conscience kicking in. Does it make sense? Well, I don't think so, but what's done is done.
Once more, alcohol was used to justify her behavior. Not a fan of that. Truth be told, I didn't think for a second that this update would end the way it did. Not in a million years. That said, Dylan and incest fans have gotten a solid update here if we leave realism out of this for the sake of progression. Oh, and Dylan really did surpass Sam, gotta give him that. L&P did not lie about that. I'm surprised to say the least. Not a fan of Dylan&incest myself, not a fan of how it went down from a story and realism standpoint, but it did happen and honestly I thought it would be worse.
One more update, and PD13 is finally over. Big question is what L&P's supporters have to endure after that, knowing he's apparently planning for Steam, his "trailer" and whatnot. That is what I'm waiting for, as PD13 really didn't have anything interesting for me personally.
Cheers
