Ok so this was a tough couple of paragraphs to read, but I think I have figured out what you meant here.
To be clear I have no problem with the setting and the story. It's a weird alternate reality, cyperpunk blend with some romance tossed into the mix to spice it up. Far better than yet another boring 'House with a Harem of Sisters that happen to be crazy about the MC for...reasons...' just as you said.
My problem isn't with the story, if that was my issue I would have stopped reading it within the first few minutes.
My issue was with the lack of meaningful choices as I said.
Another way you could rectify that issue is to remove the choices altogether. Make it a Kinetic Novel instead of an AVN.
There are several advantages to this:
1. The player gets their fill of T&A without having to figure out obscure, hidden, relationship options.
2. You get to tell the story the way you want to tell it with fewer complications in terms of coding.
3. Less coding or storyline variations means less time spent in development, which leads to faster delivery of the product and happier customers.
4. No choices at all annoys me less than choices that don't change the plot. Less complaints from me or other OCD arseholes like me.
But you should probably consult your paying customers first, I haven't paid you anything, so my opinion doesn't matter.
