What is XXXivilization?

XXXivilization is a 4X strategy game where you play as the leader of a nation in a sex-fueled world. Your sole focus is to expand your borders and ultimately conquer the world by any means necessary. It is inspired by games like Civilization and Free Cities.

Example of the CG art


Current State of the Game

At the moment the game features a procedurally generated game map for every new game, three major factions, and several minor ones, a large tech tree, dozens of spontaneous events, full-fledged character creation, plenty of sexy times and a few images.

Since XXXivilization is still heavily in development I am always grateful for all kind of feedback. Just leave a comment here or a reply in the forum, there I can also answer you. Or just join my discord to have a small chat about the game.

Latest update, Version 15

Version 15 features 45 new images and an Overview revamp that cuts done on the amount of clicks and downtime it takes to complete regular actions.


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?

This is a great game in the explore and expand genre, with porn!

Even at this stage it's fairly complete in and of itself, but the author is regularly adding new functionality.

i would like to see more tf options for the player and the ability for the player to gain more dicks or boobs.

Review by max02

Version reviewed: Version 12 on 10/09/2018

the game is not bad, but I want to see more content: in battles, in the city of the main character, because when the city develops and new buildings appear, I want to visit them, but so far this is not possible. I also want a larger map size, and third-party NPS, as well as monsters with whom you will have to fight or make peace to defeat others, or for trade relations.

The ass size not appearing at male characters is pretty annoying.

Review by colin18swood

Version reviewed: Version 10 on 08/12/2018

Firstly I am really enjoying this game, I think it's one of the best games on this site.  One slightly annoying thing is how long it takes to grow testicles even an inch in size.  I understand not everything should be instant, but it took me about fifty testicle points (like several thousand religous points) to just grow them an inch.  Maybe you could either add mays to get more points more quickly or lower the cap on the size scale.  Also, there is a kind of annoying balancing issue when you gain as much power as the game offers your character, it becomes pretty much impossible to lose a fight even on the hard difficulty.  I would suggest a level cap or adding some sort of strategy system so winning doesn't become a complete certainty.
