does anyone else have a problem with AI being either too easy or rediculously hard to the point where you have to use exploits (navy, early conquest etc) to win? i'm pretty new to civilization, but find that emperor is a bit too easy. especially on the island maps. on immortal, you struggle like crazy while the AI civs have almost infinite happiness, mass production, mass technology etc... you try to make friends with the daddy civ, but they won't have any of it and soon you'll find yourself at war with one or more MASS military civs. seriously, in my last game i was attacked by greece who allied all of the city states surrounding me, and they had a city close-by with no fewer than 9 fighter jets. then just blitzed my cities and mopped up with mechanized infantry (my cities even with arsenal's only had ~40 defense). even with average technology on the scoreboard, i was still without artillery, anti-aircraft guns etc while this was happening. imo the happiness = mass expanding strategy of the AI's on higher difficulty is broken. the mass expanding civs always scale about 10 times faster and you can never keep up unless you're exploiting the dumb navy pathing.
