But if the Duke of York was the Count of Bukhara , why would he stop there ? With Cities along the Silk Road such as Samarkand and Herat and Tashkent are within striking distance ? But , if it's just as ridiculous for the Duke of York to be the Count of Bukhara ( or for that matter Herat ) in your view , as compared to the King of Annam , or Duke of Guangdong , or Duke of Sulawesi ( Ok , the last bit is a little of an exaggeration) , they should slice off Persia from the map then. But then , you cant simulate the Mongols properly , nor the Seljuks , nor the Khorezm , nor the Timurids .
Let's face it . Cambodia might be quite irrelevant for CK Geographical region , but , are you saying that Samarkand is irrelevant to the fortunes of who controls Iran , and hence in a position to control Mesopotamia and beyond ? In that case , wouldn't Bukhara and Khiva , in the oringal CK Map be just as irrelevant ? Why don't cut off the whole of Transoxinia then ? But any successful Crsuader who has just smashed Islam in Persia would probably follow Alexanders footsteps into Transoxinia/(AKA Bactria) , if he could.
Bukhara , which is in CK1 , is a mere 200 Kilometers away from Samarkand , which IS NOT in CK1 . If I could march an army across Khorasan to conquer Bukhara, what is 200 Kilometers to me, especially if that 200 Clicks are quite flat? And Tashkent is a mere 250 Kilometers away from Samarkand . Again , any army that managed to Cross from Khorasan to Bukhara and Samarkand would find it quite easy to reach Tashkent , especially with the incentive of another rich silk Road city. Crossing from Tashkent to Xian in China of course , is quite another matter all together.
I personally would like a Map Extension all the way up to the Tian Shan and Hindu Kush and the Edge of the Kazakh Steepes . All of these form excellent geographic barriers that justify terminating the map there . Beyond the Tian Shan lies the Taklamakan Desert - one of the harshest on Earth . The Hindu Kush is a formidable challenge to cross too , and has always been regarded as the natural Geographic border of India . I'm not arguing for Punjab or the Edge of the Indo-Gangetic Plain to be included , nor Mongolia , let alone arguing for Kyoto or Malacca to be included in the game at all.
I'm just advocating a slightly saner point to end the map at . To the North , the Urals should be a good point to Terminate the map at , at the South , the Hindu Kush and Tian Shan and the Steepes of Kazakhstan . The Status Quo in CK is really bizarre - it irks me to see the map ending at Bukhara. Either terminate the map at Khorasan ( making it very difficult to truly simulate Persia) , or extend it to the Pamirs , Tian Shan and Hindu Kush.
