Bone Town got updated recently, bit of a slug to actually get through the story to unlock shit tho,
Lab Rats 2 does this, but is buggy at best, and unplayable at it's worse,
The Imperial Gatekeeper (Specifically the modded version on the page) is Paper's Please mixed with porn,Would reccomend,
Slave Matrix, older game, bit weird to get the hang of it,
Strumpets (Abandoned, bit repetitive,)
Simbros (Abandoned, 3 years ago, repetitive and broken now, look up an earlier version,)
Orc of Ambitia, same art style as Sold Girl, different positions and stuff, (MTL tho, be patient with it.)
Tindering, Would not recomend,quality is, bad.
Super Deep Throat has a randomization button, add in mods to improve that customization,
Any Illusion game has the potential, but i'd go with using a personal RNG and modifying to your fit,
(Koikatsu Party) in my opinion,
Prolly a BUNCH more I'm forgetting, my terms to search are "managment" and "character customization", sometimes "sandbox" pulls up something,
Edit: Stationmaster!, Breeders of the Nephyl-(whatever the fuck word it actually is, free on Steam,), Honey Select actually has a randomizer built in, H-Core Dungeon (Unfortunately 0.1 demo, and seems to be abandoned for another porn game,)
I'm actually debating on coding my own little game for this niche, but it won't be porn related at first,
