oh it's totally fun having warriors, and nooooooo clue how close the AIs are to rocketry until i see SAMs in their cities

, since i'm blocked by eleventy billion pre-reqs on the tech tree *giggle*
the screenshot on page 1 is a game with handpicked opponents, they were picked to get along with me and each other, but a bit on the religion-happy side. the religion angle makes it a bit tricky and interesting, but not as dangerous as the aggressive warmonger types. that's the #1 easiest way. cyrus was the odd man out there, he was the one we didn't like (except hatty, they were both jewish) ... he DoW'd mansa even! i can't remember the last time i saw an AI vs. AI war in a handpicked culture game, but i don't usually pick him. anyway...
latest game, turn after the win:
the DP with fred wasn't needed, i'd been checking to see how many i could get at once for giggles. this is another game with handpicked opponents, but a couple i hadn't tried before.
things that i do with random and with picked opponents: stay NSR/FR if there's not one dominant faith, until just about everybody is in FR themselves, before picking a state religion to run pacifism. i'd rather have the benefit for longer, but sometimes it's not safe. extra great artists won't help me if i'm dead. i check the diplo screen obsessively. if any 2 civs are miffed at each other, i usually cancel ongoing trades (OB/resource deals) with both. the last thing i want is for one of them to come by and demand that i cancel trades; that will get you a -1 with one of them guaranteed. best to do it on my own turn and not get the -1. i trade and make sure everybody is at +4 fair/forthright and +2 years of resources (to the extent possible as far as them getting along). if possible, i do what i can to help them get along. i mentioned somewhere recently, but apparently not this thread, that i gifted churchill liberalism (and one of the pre-reqs) in that game, so that he'd go to FR and then get along with hatty. i wanted her pigs, but i didn't want "traded with worst enemies". it worked. that's not something i'd have thought of a year ago.
lots of people love Liz for cultural. i like her, and have won playing her a number of times. but my favorite trait for culture is spiritual. not for the temples, but for how flexible it lets you be in politics. "change to your religion? absolutely no problem buddy!" wheeeee +1. "use your civic? why didn't i think of that myself!" +1 again. swap from caste to slavery if i want to whip something, etc. gandhi's my favorite leader for culture lately. next try will be roosevelt, and the culture slider isn't allowed to go over 20% *giggle*.
the higher the level you're on, the more likely it is that the AI's will send you a missionary. i think because their production bonuses get so big that they run out of other things to build a lot sooner. i've had emperor+ OCC games where i end up with 4 or 5 AI founded religions in my one city, yeehaw! spiritual is so priceless for that--change when they ask you to, then change back 5 turns later so that the others aren't mad at you. the +1 stays, the -heathen everybody else gave you for those 5 turns goes away.
sometimes somebody gets mean and declares, and i'm totally gonna lose those wars so i quit (victoria i am looking at you ... capture my city 3 turns after i build sistine chapel, that is just plain RUDE!!!!!!). but i put a lot of effort into diplomacy, and if you were watching over my shoulder you might not be able to guess whether i was going for cultural or diplomatic except by the techs i pick

. trying the usual "build up the power graph" is too much effort for me, feels like wasted hammers and i'm lazy that way. so i do it by pulling the "i'm harmless and nice and sweet, and we get along so well, don't pick on me ok?" act. sometimes it works, sometimes it doesn't. i of course like it better when it works.
