I suppose this goes back to that general lack of creativity going around right now. Let's just go over and over WWII and afterwards. Why no WWI games, even??
Fallout New Vegas was different in how a possible central enemy faction was a group trying to be a new Roman Empire in post-apocalyptic Nevada and kind of failing. But then, that's a RPG-shooter, not a "modern" shooter.
Really, games placed firmly in older historical settings in general might be nice. Seems if you want to fight things with a sword these days, you *usually* have to do it in some "alternate world" fantasy setting i.e. Skyrim--and then magic always gets introduced into the equation. How come I've only been able to fight in the Hundred Years' War in Age of Empires?

The Mongols were actually pretty cool. They conquered bloodily and horribly, but in their empire shit was awesome. There was absolute religious freedom and it was a very secure place. It was said that a man could walk from one end of the empire to the other with a plate of gold on his head and never risk being robbed.
That security was a enormous boost for land-based trading routes, which lead to great economic growth for everyone, etc.
TL;DR Mongols hardly that bad, certainly not on par with the Nazis.
Not to get too much into a historical debate, but the Mongol Empire's brand of conquest was SO over-the-top horrible that I, personally, don't think anything they did or did not do in the conquered regions afterwards makes their Empire any less "evil". The Mongol attack on Baghdad alone killed probably hundreds of thousands of people and destroyed the greatest library of the era, and their invasions of the Middle East area overall are a prime reason for why the region is unstable to this day.
As for their sometimes-overly-vaunted security, it was enforced by the threat of outright killing everyone in a town or region, and only happened because the Mongols only cared about getting their regular tributes, not because of any actual humanitarian urges. As long as you bowed down to passing Mongols (figuratively more than literally, mind) and paid them regularly whatever they wanted, they didn't actually do much positive *or* negative in those regions. Genghis Khan just wanted his and the Mongols' name to ring through history, and to get a lot of money (and, admittedly, get them out of that desert). And he killed thousands upon thousands of people to achieve that. The man was evil, and being brilliant only enhances that fact (Mongol military was perhaps the first "modern" military in its organization level--and again, that incredible organization was used to slaughter people for decades and centuries).
TL;DR It's hard to say any group in human history was "equally as evil" as the Nazis, which is one reason why Godwin's Law exits, but the Mongol Empire was a very negative force on human civilization--and one that lasted a loooot longer than the Third Reich, to boot.
