First Appearance: Sid Meier's Civilization (1991) Genghis Khan must either be a glutton for pain, hate his people or just want to demonstrate exactly how tough he is. We are inclined to go for the latter option. You can be involved in a game of Civ where everything is going right the Barbarian population is under control, trade between civilisations is booming and everyone is happy with the distribution of land yet Genghis Khan will still be skulking in some remote corner of the world amassing an army to slaughter his rivals. While his upsetting a potentially peaceful game of Civ can be incredibly frustrating, it would be a crime to not credit Genghis as being tough the guy simply loves war, pillaging and fighting. Even if it will result in a consortium of other empires ganging up on him, the ultra-aggressive Mongolian will still cry havoc and let slip the dogs of war as he simply knows no other way. Firaxis portrayal of the historical leader is far tougher than his real-life counterpart who is supposed to have died just from the impact of falling off of his horse.
