My god. I've just sat through reading three pages of this drivel and am spent. I cannot believe that so many people are so uptight about "cheating". What are you so upset about? The AI zigged when you thought it would zag? Occasionally that spearman makes a run at immortality when its the best that the AI can offer to defend against your modern armor? The galley that somehow makes it through the high seas to your shores and drops a settler on your one and only open coastland square?
Why can't we get past this? It seems to me that players get their strategies together, then get angry because the AI doesn't perform according to the "rules". You know, I haven't read exactly through the manual, but as far as I can tell the rules there are for the player, not for the AI. The "cheats" make the game more interesting. Guess you should have broken that spearman down with a few artillery blasts before sending half your army at it. How stupid are you who sends ten tanks at the biblically superior spearman anyway? Send one and if it dies, you know you're in over your head.
Maybe the AI programmers realized that on a map where the two main land masses are over five squares away you won't contact anyone until the late middle ages. How boring is that? Lets lower the sink percentage for the AI in these situations to make for better gameplay. We can't do it for the player, because then they'll know how far away the nearest landmass is without actually looking. We can do it for the AI, because after making this adjustment we'll just remove that information from the AI Civ's "memory".
And while we're at it, when the player is in the late modern era and goes to war against an ancient era civ it will be too easy. Lets make some of the ancient civ's units a little tougher to make a game out of it.
While we're talking about "cheats" here, lets not forget the biggest "cheat" of all. The player gets to do whatever he wants in the game, while the AI only gets to do what its programmed to do. Sure, maybe a patch will even it up a bit here and there, but how long does it take to overcome this - "Whoa! Never saw that before. Guess I'll have to do this from now on." Does the AI get to say this?
