So, um. Which leaders will go to war with you after you've forced them to capitulate?
I was playing a warmongering game on Noble difficulty today (something I've gotten much better at now that I know about build-Queues and rally points, lol) and I killed the Egypitians (to my east) early. A few turns later I declared on the Sumerians to my south. After taking 4 of Sumeria's cities I noticed my research slider was at 40%, so I contacted him and got him to capitulate, along with giving me all his techs and resources. Anyway, after that I started building my economy, but I still had an army twice the size of anyone else, and since Sumaria had my southern flank protected, I moved my army to the Northeast where Arabia was looking nice and juicy. I figured I could spend my army taking a few Arabian cities while the rest of my cities built up their economies. Anyway, after I declared on Arabia, Sumeria stopped trading with me. At which point I told him to give me the resources back or it'd mean war. Every other time I've done this to a vassal-- including a vassal I'd never gone to war with-- They were happy to give me everything they had. This time was different. Sumeria took the war option. At this point I'm fighting a battle on two fronts, but I just discovered Rifling, so I switch all my cities back into army production, and in a few turns I took two more Sumerian cities. At which point, Sumeria Vassals to China, which is the only civ in the game that comes close to my power level... Not to mention I'd been carefully making China my friend. Anyway China happens to be right behind Sumeria so I'm immediately swarmed by every mounted unit China has.....
RAWRG.
I guess that's more info than you need, but gawd! I've had civs I was about to wipe out vassal to strong civs in the past, but I've never had a vassal DoW on me and then vassal my best ally and trading partner. I simply must know which CiVs are capable of this sort of duplicity, and under what conditions they'll do it!
Thanks!
