Hello. I've been playing Civ4 on Noble for three months and I think I'm almost ready to move up one level. But only "almost", because I've still got to figure out one thing: how the heck can the AI outtech me when I make 2x as much gold as them? See the attachment: I'm by far the richest civ, earning 2x as much gold as my richest rival (Spain). And it's not recent: it has been so for dozens of turns. I also know for sure that Spain does not have contacts with civs unknown to me. Still, they're several techs ahead of me. Even the lousiest civs are not that far behind me. Now, before you ask: I have not been warmongering like hell, or favoring religion or GPs at the expense of science. On the contrary. My whole territory is improved. Every city has a MP and a Lib. And I have been vigilant not to miss tech trade opportunities. Still, I seem to suck at research. Or would it be possible that the AI cheats more badly..., er, I mean, benefits from more "advantages" in tech than in other areas? (like: 10% discount on buildings but 20% in tech) That would explain why I can easily beat them in every area, except tech. Any clue?
