Just out of curiosity, how would you want it to be implemented?. I mean, what decisions should the PC now turned into NPC make?. Should those decisions be chosen from a predeterminded trope (chad Ian, cuck Ian, slutty Lena and so on) by the player at the beginning of the game or should they be dependant of the choices you make with your remanining PC?.
Totally agree, I just can assume that Eva took the path with less work involved not having to create additional art and writing for random beachgoers.
Also, just to clarify, the drama with Wade doesn't only happen on Ian cuck route, I think it happens in any cheating Lena path and it even happens if Lena and Ian are not dating and Lena fucked Axel before taking the train (the writing and Ian's reactions make no sense at all on this particular case imo). I'm not going to start again with Wade bashing, but a random hot beachgoer would have really made much more sense on non Ian cuck routes.
Problem with Alison's path is when you are dating her, love or not, without Jeremy or any other drama. It goes from a impregnation fetish to using a condom as the major point of drama. And this is repeated during the last two encounters without any significant change.
I managed to make a save where Ian fucks Cindy and Wade amicable says he should break up with her. It's kind of difficult and you have to make an effort to mantain wade_cindy relationship at 1 and not going to 0. If you do that, you can make Ian ask Wade at the beach "Are you even happy with her?" which puts wade_cindy relationship at 2 and you avoid all the drama with Wade and Axel's Peoplegram post with the photos.
