Harsh truth is harsh and, in this case, useless.
If the guy is doing something wrong, a useful post is one that teaches him how to do it right.
But how about a game forcing you to do the same thing over and over again, like so many people described here? Yes, people come here all superior talking about their "winning strategy" that it's all the same and don't realize what this means.
It means the game has a "recipe" about how you should play it, if you don't follow it you are a "noob that got pwnd" and that means another major failure in Civ 5 account.
So to all of you who think in themselves as big-pro-master-players, thanks for showing one more reason to think that this game is a failure. You're not special, you're just following a ridiculous recipe to win. It's the same as playing a RPG game knowing what answers you have to chose to get what you want. Big deal.
Edit: and builer680, don't think that my reply includes you. You're one of the few person in this thread interested in analizing, discussing and providing actual strategy to overcome the problem of the OP.
