I really don't get it. Why am I struggling at this prince level game when the other one I had over a 1000 point lead? Something is really buggy about this game. I couldn't have gotten that much worse at this game in just a few hours.
I know both games were at Prince, unless for some reason the Earth map default is warlord or something?
I don't understand why I'm struggling so much with happiness and gold when my prior two games I had no gold and happiness problems. I really am worried about losing this game. This really seems like a bug to me. I'd like to post save games of the games in question, maybe someone else can come up with answers. The only differences between the games is one is an Earth map, the other is archipelago, and one other difference is I left all the victory conditions enabled, where as my prior game only domination was enabled (I thought this would give more challenge, as the AI would concentrate on warfare, but it didn't work).
Anyways, I failed to get a religion. What gives? How can they find religions so fast, but I need 600 faith, and I can only get 1 or 2 a turn from having 2 cities with 2 shrines? The AI clearly has to be cheating to take all the religions.
I think you're drastically underestimating how much small differences can affect the game.
You can have 2 more production early on for free just for having better terrain - you might not even notice it, but you'll hit your worker a couple turns earlier, which will give you even larger bonuses fast, which will hit your first settler 5 turns earlier, hit your second city that much earlier, give you a resource to sell that much earlier, and so on and so forth. You can easily snowball out to be 15 or 20 turns ahead just because you had a better start and made use of it well, which can very well mean you win a war instead of fighting to a draw... and now you're the runaway civ on your continent instead of being just another player.
As far as religions, they might be getting 1 or 2 a turn from several more cities than you, or they might have three religious city-states feeding them faith, or they might have a strong faith producing Pantheon, or they might hit two faith goody huts, or they might be one of the various civs (Celts, Ethiopia come to mind especially) that have bonus faith.
In addition, AIs vary from game to game in how much they will expand, both on how the map is arranged and in terms of their own preferences, plus different leaders have different personalities. It's perfectly possible to get a game where the AIs don't expand and don't want to fight, it's just unlikely; usually at least a few will want to expand.
Point being, small changes in start location, goody huts, neighbor behavior , etc can add up to huge differences in play experience.
