I spend a lot of time on this, on Noble, various strategies and nothing works. I can build say 6 cities by IAD and the rest of the game I am hamstrung by high maint. costs. Yet the A1 can build larger number of cities, bigger armies etc, seemingly without regard to maint costs. I also notice how the A1 always avoid unfriendly huts and always know where barbarian cities are as soon as I open borders! As though FOW does not exist. This method I struggle to get to 30% research. This game should be about fewer, better cities, so I tried building fewer, and yippee with research at 90-100%. I can only have a moderate army (Hyuama), and pleased with most. I find I am bottom of the league by some margin as a result. then Wilhem of all people who is pleased, suddenly decides to attack me for no reason - end of game. I did not adopt a religion though I had Poly, mono and Confus as careful to choose the right time to do this. Not playing a Mod and builder, not warmonger. I would have built a slighlty larger army had I realised this idiot would suddenly become a crazed maniac and behave like Monty. I really do not want to play this game again - it is a waste of time, not enjoyable unless you play at Warlord level which is no challenge, and I hope Civ 5 is free of the AI cheating for want of a better word. I am moving over to EU3 and NTW which do not suffer from these anomolies. For info I attach a save file, but this game I was just experimenting. 2-3 turns later Wilhem declare war - frustrating. Admittedly I played this in 2 hours was a kind of a rushed job.
