I've been playing a game as Mongols - standard, pangaea, Immortal difficulty - and doing pretty well so far but I have a few questions. I basically rushed to Chivalry using a GS from Meritocracy for Civil Service, plus several RA's, allowing me to complete Chivalry around turn 70ish (I blocked the whole bottom of the tech tree at Mining since I had no mining resources). I had built/bought 4 horseman by that time and saved the cash to upgrade immediately to keshiks. With my 4 (eventually increased to 6) keshiks, plus the khan, I conquered 2 AI civs by turn 110 or so. It took a little while longer than anticipated since Alex declared on the first civ I was going to conquer (Egypt) 2 turns before me, and I waited for him to lose a bunch of troops and sign a peace treaty with Egypt before I started my push. This allowed me to quickly take Egypt and Alex. However, I have a few questions going forward. 1. My map is naturally split down the center with water and mountain barriers, so I will need to go NE to take 2 civs up there then circle back to the NW to take out the remaining civs. This will take some time so I was wondering what the window of opportunity is for keshik dominance - for example, approximately what turn do they lose dominance (or what level of city defense does it become difficult to take with keshiks)? 2. What unit do you normally use for final city taking? I have been dragging around a longsword to do this and he holds my horse army back. 3. What promotions do you normally take with keshiks? I have been going for 3 in either the ranged smooth terrain or ranged rough terrain to start, but I guess these will be useless if I eventually need to upgrade my keshiks to a more modern unit, i.e., if I don't make it all the way to the last civ during the keshik window of dominance. Would taking city siege bonus have been better?
