An interesting question, to be honest, apart from the black market for monsters, I can’t really remember anything. But recently
this game was posted here. In it, you can physically kidnap natives in order to subjugate them and make them your slaves/settlers. The game is not finished and I previously tried another build from another site, but that’s all that comes to mind on the topic of “kidnapping people.”
I also looked at soldgirl town, which is on this site, the synopsis sounds interesting, but the size of 300 MB is a little confusing, I feel that it is impossible to put any high-quality renderings and well-developed mechanics here.
