Not really a good domination player, but I'll give it a starting point and see where it goes from there
Won on turn 320. Built 3 tall cities (and claimed a few AI capitals I took, most were puppeted), but a few challenges I ran into, mostly through my selection (or mis-selection) of AI opponents. England was able to build the great wall in mine, and it had an army of longbows. That shredded through my trebs and musketmen I had at that time pretty hard. Also, I tried hitting denmark with composites and swordsmen, but they had zerkers, and that one I "lost" (although I took a peace deal that gave me a city)
Ended up cleaning up with Cossacks and Artillery. Definitely interested in seeing some veterans to improve my domination strategies.
