The Jaye and Alex relationship is the central pillar of this AVN.
On the Jaye only and the Jaye/Mallory open relationships - I did not have the antagonistic Jaye experience you did.
I found that by doing dick things to Jaye - she is true to her character and she does dick things back - she is not one to back down.
If the MC does not care about her, she gives it right back, to a degree.
Even through all of this, though, Jaye still tries to salvage something of the relationship that she and Alex had - honoring the wishes of both her father and stepmother - Alex's Mom.
I don't see why it is strange that she would still try, given the way this story is told and the relationships involved (Jaye and Alex both had great respect and love for their biological parent and their stepmom/stepdad)
I suppose the devs could have taken 9-12 months per update and created much deeper paths for Tara, Lisa and Bianca for example, but they chose to keep their focus on Jaye and Mallory.
I think they did a great job for their first AVN.
There will always be other women in an AVN who could have gotten more screen time.
I like Bianca just like I like Lisa, Tara, Erica, and Sophie but I do not expect the devs to provide a major (or even minor) LI path for each.
IMO - it would be like complaining that
George Lucas did not provide the proper Love path for Princess Leia and Chewbacca in Star Wars.
Jaye might not be your preference but the devs wrote Alex with certain boundaries and, outside of game over moments - like letting Jaye drown (a valid choice the devs Did give those who chose to compete with and not care for Jaye), he stays within those boundaries.
Alex has the ability to let Jaye die but Jaye never gets to return the favor...
Alex has multiple opportunities to turn the Jaye relationship into something bad - and Alex acting like a brat holding a grudge is part of how this happens.
For the actual Jaye path (committed to Jaye and Alex does not cheat) - I found it is one of my favorite AVN love stories.
I know others prefer Mallory or Tara or complain that they have been forced to take a particular path (Jaye).
When I tried an AVN and found I hated the way it did certain things - if I hatred that experience enough - I stopped playing That AVN and moved on to something I liked.
When I treated Jaye well - she was not a spoiled brat - she was a loving and thoughtful companion who was a joy to be around.
It seems that we each got the Jaye experience we chose in our most recent playthrough.
Cheers!!
