I started a game with Assyria this weekend. Played a lot because I hurt my back Friday and couldn't do much. King, standard speed, large pangaea map, raging barbs, sparse resources, and one less civ than whatever the default number. It's a very odd-shaped continent and I still haven't explored the whole perimeter yet, in the modern era and I have the Great Lighthouse.
Tradition, Honor opener, Commerce, Rationalism opener, Freedom. (I have foreign legions and artillery and leftover siege towers for their sapper bonus, everyone else still has muskets and knights and trebuchets -- but it's a really big map with a lot of rough terrain)
As soon as i got 2 siege towers I captured Rio de Janeiro and another city which I razed, and went from last place in science to third, and there were no more techs to steal from Brazil. I could have wiped Pedro off the map, but I was having happiness problems, so I took Brasília in a peace deal (it had marble) and set my sights on Germany.
By the time I got my happiness positive again (I had lots of truffles and not much else; nobody had any spare luxes to trade) I was the tech leader. Eventually I did DoW Bismarck and took 4 or 5 of his dozen cities (razed all but 2) but I stopped short of capturing Berlin. One of the cities had Forbidden Palace and another wonder and that was enough for now, and I'm not ready to piss off my good friend Gandhi yet. We've been denouncing the same other leaders (Brazil and Egypt) and he has been overlooking my warmongering.
Somebody has eliminated Mongolia; I think it was Shaka, but it
might be Egypt and then Shaka took the Mongol cities from them. (that would explain why Gandhi hates Ramses so much)
I did not expect to be the technology leader so quickly. (I use trade routes to determine if a civ has *any* techs that I don't, and none of them do) It kind of takes the fun out of capturing AI cities.
Does that mean I should be playing at a higher level? I also think large continents might be a better map for Assyria; eliminate the other civs on your continent before Astronomy, then work on gold and infrastructure so you can crank up your war machine later when you meet the rest of the world.
