It feels more like fairly even content amongst Alexis, Layla, Nikki, and Cara. Erynn is sprinkled throughout like Elena. I haven't done anything crazy like count dialogue or images, but I would say they are all fairly equal. And the story represents that. I guess if someone is only counting specific types of content (i.e. lewd) then it would seem unbalanced. And if you are approaching it from the side of storytelling, then I would agree that Erynn has not had an appropriate amount. Still, I don't seem to have any of the problems with the story that some have.
The Alexis story is the most well-rounded and developed so far. So, it makes sense that some people would appreciate that content more. And at the same time, it explains why some people do not like Alexis. But the story is still being developed. A lot can change.
As mentioned above, Erynn is there when the MC needs help and comfort. Alexis/Nikki/Cara fills the sex and love area. Layla is climbing, in regards to sexual awakening. Flashbacks take care of Iris and Lakeyn. And most of us are anxiously waiting to see if there will be Elena and Valeria content. And of course, you can see my bias for characters now!
Well rounded is not what i would call Alexis story, her initial actions don't gel with her later character, the "hashing it out" is fast and argumentless, ultimately just "i forgive you and let's go back to fucking" and for quite a few updates now she's been stuck on "let's go on a date" routine, nothing happens, seems endgame state already... she gets plenty of "action" but her story begins and ends on "i love you so much".
Nikki(applies to Cara) due to being a "out of town character" gets episodes heavily focussed on her and then dissapears for a couple... and after being radio silent for a while here she is for another go around... can be boring if you are making a solo playthrough i tell you.
Erynn, i just think Nyx is hitting a little too hard with the "serious drama" on her case, i was very into this game when there was, Alexis vs Erynn drama... when are the sisters going to find out you been messing around with both... girl vs girl drama, that type of shit, it was fun.... and it's quickly being written out.
Plus Nyx seems to want to play her dramatic tale to completion before we can actually do anything with Erynn, for those of us who got invested early in the character it's getting increasingly frustrating, close to a real life "it may not be worth the effort".
I honestly never felt like this in a game, even those that hit us with heavy drama and "slow burns" i could see how i was getting closer and closer, Erynn feels like one step forward 3 steps back, repeatedly.
Layla, Elena and Gabi, feel like good stories to me, even if Layla/Elena is rather slow, it's constant progress, good long form storytelling, it's slow but there's enough fun moments to hold you through and you can see story is progressing.
A lot of people seem to love Valeria while i'm confused why Nyx is still bringing new characters this late into the game.
