>>3081876About a year ago I had an idea to make a porn game in which elven empire destroyed village of orcs and enslaved them to work in the labour camp where you are the head of it. In terms of gameplay you have to manage finances, resources, assign jobs for slaves, keep an eye on health, mood and discipline of both orcs and elven guards, and brainwash/indoctrinate orcs with various methods from body-altering potions and hypnosis spells to torture and religious education.
But the scope of this is quite big, it will take a long time to make on top of that making games is hard.
