That's the whole point right there, the survival of both (the living vs the dead/zombies) sides. the zombie were just trying to do the same thing as the living, trying to repopulate and make their clan(side) bigger, better and stronger. and the zombies figured out that if they breed the living females the could get specials out of them which is why they kill the males and take the females back to their nest to breed them. now, is any female going to do that willingly, hell no, which is the reason for the zombieAt the beginning it was important to create the self-centeredness of this group of three people in an apocalyptic world in order to provide an explanation for the breaking of social and biological rules, but now the game, or perhaps better the story, is in danger of failing because of this.
You're right when you say - incest, more incest and then more incest - it's getting tiring and not really anything new.
The game isn't shit like you say, it's still far better than many other games and I still enjoy playing it. But I'm starting to ask myself where it's headed now.
"when everything went to shit" - I assume for you that was the time when the zombie rapes were removed from the game. The problem is, according to the author, they were not relevant to the story but only an end in themselves. Rape of women was made into the game's theme, for the developer's customers who like that sort of thing. (I would like to expressly say that I am not judging anyone for their fetishes!)
The idea of rape as an expression of a driven evolution of the zombies could have been told in a story-relevant way, but it was never planned that way (author's statement!).
At this point, you can really say that the author has replaced a non-existent vision or direction of the game with "no" (at the moment recognizable) vision/new direction.
The basic idea of the game still supports the story, but for me the signs of wear and tear, purely emotionally, were clearly noticeable in the eighth update that was just released.
For all those whose toes I'm stepping on with my post - I won't back down from it. It is a personal judgment that I make based on my reading experiences and life experience and therefore cannot be seen as the absolute truth.
