Karakorum is surrounded. It is one of the three remaining Mongol cities. Legions of Sibir biotroopers close in on the city, which is defended by a single tank-thing unit and a caravan. Genghis Khan has two options: flee or die. Or, well, leaders can't die until all their cities fall, so he actually has only one option: flee to one of his other cities if Sibir attacks.
Will Kuchum grant Genghis a warrior's death by taking Karakorum last? I doubt it.
Vietnam and Sibir give me flashbacks of the eternal meatgrinder. the word "Bamda" makes me shudder.
