Civ5 Barbarian Tribes (Playable Barbarian Civ) 2016-10-05

This mod will try to alter normal gameplay by giving the player control of a special civ. This civ has been changed to represent a barbarian civilization, forget about culture, you will never go to space, diplomacy only to delay the conquer... A lot of roleplay is involved to make it work, you should act merciless, pillage everything, raze cities and try to rule the world as soon as possible before the civilizations grow in power and technology.
