This is my first game, XXXivilization. It is an attempt of having some kind of 4X strategy game a la Civilization or Heroes of Might and Magic in a NSFW setting.

You play the ruler of a tribe and try to establish your kingdom and conquer the world.


The game is now also available on patreon, it would be awesome if some of you could support me there: Patreon

Update, Version 8 is now public:

This version brings a lot of new changes: A new enemy empire has been added to the game, you can now have sex with your prisoners and "train" them and a lot more stuff, give it a try if you haven't played it for a while!

If you are intereseted in the detailed changelog you can view it here.

You are the newly promoted leader of a small tribe somewhere in a distant land. You have been given the task to lead your people to new prosperity. To achieve this you will have to conquer new lands, build up your capitol, promote both religion and science and last but not least become a greater person than you are today. 

Whenever fight is inevitable you and your army will have to fight in the traditional way of your tribe: By seducing your opponent and fucking them until they pass out. It has always been this way.

Are you ready for this challenging duty?

  • A new rival empire got added to the game:

Wonderful. Simply Wonderful.

This game is just about everything you could ask for: Well written dialogue, the strategy and gameplay of Civ(albeit somewhat simplified), a UI that isn't painful to look at, and the transformations that we're all here for.

Even though this game is still obviously in the early stages, the framework that has been layed is quite possibly some of the best this site has to offer.

My opinion, game is really good (i love the strategies with big research trees), good writing, good gameplay.

My own wish: a lot more of events and sex scenes (and they variety)

I really love the fact that now you have an actual adversary- Thank you for that. Now, i would like to marry the Futamazon Queen, do you think that would be a posibility in the future? maybe have an actual harem, with wifes and housbands. And maybe heirs...

I really like this game! It's got a really solid framework so far; right now the biggest issues are:


balance fixes, both in resource mangement and in combat

Lack of content


The latter I know will be fixed as new updates are pushed out; I really look forward to seeing more from this game.

This was a lot of fun, and I'm looking forward to more.


Ultimately, it's early days for a game type that is huge and requires lots of content. It'd be interesting to see if worshiping Abstencia has any value, but altogether I'm pretty satisfied. Early grinding and training is a must.
