So I'm pretty much challenging myself to beat immortals now. Sometimes I win, sometimes I don't. When I don't, the main problems I get is the AI overpowering me with units and troops and generally cause chaos. There is also the (very) sneaky move some AI use to ally a CS next to you and the next turn BAM you have 4 enemy units at the back of your frontline. I need some advice on how to fight the AI. I've read quite a few guides here and there, and most say "Civ 5 AI is stupid. I can defeat their entire army with like 5 units without losing any". Looking on the strategy section, many of the guides simply say something like; Fight the AI, defeat the AI, take a few cities." What they don't really specify is how to beat the AI armies. I've tried to fight them more than several times, and each time I barely come out on top, unless I have an overwhelming army (which is kinda ridiculous since it sucks so much money). My general opening is liberty into spamming as much city as I can in my space (usually I hit 7 and have to stop because of happiness and gold, as well as AI threatening me). Am I supposed to not give a to the AI? How do I manage to spam so much city and many of the guides say to (20 cities, says http://forums.civfanatics.com/showthread.php?t=503798) How do you balance between income, army, and city?
