So it is wrong to critique the premise of a game that touts about realism, make sense. You can have tons of different ways for a plot like this to be believeable. 2030 in our world is not one of them, as the author said himself. It would have to be further in the future. something like this could happen in our world on a micro scale with consent from all parties, but that is not what this story is about. If I made a game about an orc cum bender in NYC that would control his sperm to impregnate all the women in the city and presented the game as believable and realistic. I would hope someone called me out for that.
Yeah, the premise that its realistic can surely be abandoned (on more than one counts, the game also misrepresents femdom to a great degree, not realistic at all). But I wouldn't ever assume or require for an adult game of all things be an accurate sociological prediction. On the other hand, a sci-fi setting can be set up with sufficient axioms to lead to whatever social arrangement you want, not limited by consent of the parties or whether it could actually happen. Think of Lord of the Rings, yes its fantasy, not sci-fi, but the idea stands, namely: you can in fiction build a consistent, yet wholly unbelievable world!!! Fiction be it fantasy, sci-fi or just an allegory, can freely set up any world which does not tie back to how our real world would allow such a thing to occur.
However, my problem is different tho: in adult games, the world and premises are secondary, they are set up as they are precisely to ALLOW for the kinds of fetishes it wants to portray. When I hear the criticism that a particular set-up is not realistic, I always hear this instead:
"if it were realistic, then the fetish you portray would not be possible, and since I detest the fetishes you portray, I command you in the name of REALITY to cease and desist (it should be realistic precisely for YOUR fetishes not to work), and make my fetishes which are compatible with reality istead"
- its just a convoluted way of saying, I hate cuck content and perhaps even femdom content.
In my opinion people use a world-setting as an excuse for their fetishes to have an "explanation" and not make a world first and THEN think what fetishes would fit into that second.
The reasoning goes like this: I want to make lets say a game where all females are subjugated slaves, what premises and world-setting should I use to have a fictional world in which this makes INTERNAL sense and not I want to make a world, and then put my fetishes into it, if the world I created allows for them.
