I tried this scenario as the romans aiming for a *conquest* victory... *not* domination. In fact, I turned domination off as a victory condition because it's hard to get to "conquest" without hitting the domination conditions first.
As noted, Europe is crowded, but it worked to my advantage. I quickly got iron working, and sent my Pret's out and took out the spanish, the germans, the french, and the greeks. That gave me most of europe and scandanavia. My first "real" war was taking on the russians, but I destroyed them too.
I next started a war against the Mongols, but after I crushed them, they became a vassal to China, and the war stopped.
I turned my attentions to Persia next (stupid, I should have waited the 10 turns, then continued on with the mongols *and* china). After crushing Persia, they became a Vassal to China. But it was worse because Persia had been fighting, and beating the Indians. So, India *also* became a vassal to China.
By this time, we were hitting some of the modern era, and Britain, with just five cities, was out teching me!!! So, I launched a simultaneous invasion of their major cities and destroyed them in 10 turns.
So now I turned my attention back to China. This was a very frustrating war because it was the combined China, Persia, India, Mongols lands. Granted, I have a more powerful military, but the border was really, really, long.
This is about where I've stopped. The frustrating thing is, I *cant* win by conquest. there's only about 150 years of game left. It will probably take at least 50-75 years to finish off all of China and their vassals (they have a lot of islands). There is no way in the remaining time to take all of Africa and America.
I keep hearing that vassals count as conquest, but I don't believe it. Every time I vassalize someone, they're still listed as a rival left to conquer on the victory conditions page.
So, I plan to start over, at some point, I think I'll do it as the Persians (I think the Charismatic trait is most important to a conquest game). I figure I have to conquest all of the "old world" before 1700. Then, I could spend 100 years preparing to invade the americas....
