no it just rewards interaction
That's basically what I meant - I rarely interact in forums, or anywhere online for that matter. Chronic turbo-lurker.
Right, so I may as well throw in a few games I've played to keep the thread going:
Inseminator, a game about using dark powers to expand your influence over a city, which uses "turns" which last an in-game month, allowing you to eventually recruit your own daughters - stats are largely based on those of the mother. Magic can also be used to age-up your kids so you don't have to wait as long to get to them. Still in development, so I'm not really sure what the end-game is - though pregnancy is a central theme to the game. The gameplay loop is mostly "meet girl, corrupt girl, get her into your harem, and get your harem pregnant as much as you can." It's supported with a very slow-burn grind to get yourself established financially, so that your immortal MC doesn't have to pull shifts at a convenience mart anymore and can focus on building power.
Breeding Season is an old Flash project, in which you breed monsters to maintain a ranch, that directly inspired games like Cloud Meadow and others like it, as it was the collapse of that project which lead to Cloud Meadow being spun off of it. No longer in development, you can still find playable builds out in the wild here and there - if you have a working Flash player! Went through at least two iterations of art style before the end, so some of it looks significantly more scuffed depending on which build you find. After a few generations of inbreeding, though, you were forced to have to reintroduce some fresh genes - otherwise you'd be left with monsters with only severely detrimental traits, if any besides "inbred." The original art style gave the monsters big googly eyes when that happened, so you'd know at a glance.
Neko Paradise has you stuck on an island where no males are born and all men eventually die off from an incurable illness, requiring you to have sex with every character there to keep up both your own health and the population, including your daughter. One character has three states, femboy, tomboy, and tomboy futa, which are mostly interchangeable except for like two scenes which are gender-specific, in case you want something like that for spice. Not sure how the femboy-version survives the "all males die off" disease, though. Anyway, so far there's pregnancy content for like half the roster, from pregnant sex to birth to making them pregnant again, plus a short "in the future" scene for each showing the firstborn kids as they get a little older - at least there was, until basically everywhere you could reliably find new versions took them down and banned them. I'm pretty sure even Patreon axed them, though I haven't looked in a while. Again, though, you can still find older versions out in the wild - including paid dlc, which I wasn't a fan of for a still-being-developed title.
