Doesn't Carnal Instinct have futa and gay content? I'm 100% positive about the futa, however I do genuinely ask about the gay content, since I don't really seek those out in the game.Sorry bro.. i i ... i dont get the joke.
I don't know if you're being sarcastic, realistic or want to have a game like this.
There are already quite a few, being only 3 of the most iconic, although only two come in with Furry/Monster girl themes (Carnal Instinc and Breeders of the Nephelym).
Sapphire Safari, a mostly monster girl game, has futa as well. The protagonist (should the player choose male,) is the only male character.
So you could probably pick the female character and do lesbian scenes. That's gay, I think.
There is also Archipelagates. Combat with both straight and gay sex, furry and 3D. Plus it's nice to look at.
I won't be specifically looking for homosexual content, but you sure can! You just got to look. There are lots of games hidden in nooks and crannies.
Popularity shouldn't be a standard.
