Are there any other farming sims you recommend for someone who has only played Breeders of the Nephelym?
Well there's the dead project that BotN is based off of (
Breeding Season), but that one is infamous for being the prime example of a game going through development hell, and then there's a bunch of other little games that are similar enough and fall under the same few tags such as management, but really there is no "decent" farming porn games out there to the point that you could just get a few mods for Stardew Valley and have an equivalent if not better experience than some of the ones you could find elsewhere (I have been looking for years).
There's also
Portals of Phereon, which has more of an adventure aspect to it than Breeding Season and BotN, although the last time I played it I found it to be lacking in a few areas that would make it fappable imo.
If you're just looking for games where you are in charge of groups of characters, then I'd have to recommend
Free Cities since the community has kept different versions of that game going (primarily the

), although it is almost entirely text based, but you can run a dairy where you can milk slaves of various resources.
Adam and Gaia is also heavily text based, but does feature images, breeding, interspecies breeding, incest, and so on and can keep someone entertained for a few hours before it gets too tedious.
Really it heavily depends on what exactly you're looking for since there's roughly 600+ titles that have the management tag on this site (without the ai tag that aren't VNs), but for the most part very few games exist that are specifically pornographic farming sims, and even less that are decent considering BotN is probably one of the better ones out there, even with the practically dead development pace.
