How early did you get vassalage, to be able to capitalate civs that close to you?
Yup. Even Monty and HC got vassalized.
I had a naval fleet to take on Toku, if he didn't capitulate with His master Qin shi huang, but he did anyways.
You vassalized all the other European civs? Wasn't your core pretty crowded. Did you perhaps manage to eliminate any of them purely by cultural pressure?
Nope. I Sword rushed Spain and Germany, so my only opponent left was Elizhabeth and Rome.
I Had 2 cities pumping out 1 unit per turn for every turn that I was at war. I used Musketmen to overrun Catherine and Alexander ( I'm serious )
Anyways, When I attacked Monty, I hit him in 5-6 places at once. I never built an aircraft though, aside from Stealth bombers for show. I was advancing too quickly. I also never used Spies. It was Plan A, But I couldn't churn out enough EP, so I simply went for siege.
One of the key points in the game was getting Vassalage BEFORE either Bureacracy OR Machinery. Early in the game I was thinking " Gee, this would be an awesome place for everyone to kick my arse", So I got the civic when I could. It helped keep wars short.
I attached the Replay. Just stick it in the replay folder in your Civ directory.
The only civs that died were the Americans and the Spanish. Monty killed the Americans ( Shame, if he hadn't I would have had more trouble rooting them out from North America ), And the Spanish died because of their only capital, and Sword rush.
