I bought the game this month and have had time to play a couple of games. There's something I don't understand about the AI teching. I can have double the science of the AI and yet it can somehow have researched as many or more techs than me? What's going on, how is it keeping up? Currently I'm playing an immortal standard game as the japanese. I just hit the rennaissance, I have universities etc. Most other civs have had half of my research output for at least 50 turns or so and yet they are still equal to me or ahead in techs.I don't believe they have unlocked spying yet? It's not just one or two, but basically all of them. Even the weakest Iinitially I thought it was because I was playing wide. But I found out last week that the Civ 5 city research penalty doens't apply in civ 6. Is it because the AI uses eureka moments/ inspiration far more effectively than I do? So they only ever research half of a tech and let the other half unlock with some inspiration? Following on from that, what's the best way to get ahead in the tech race mid game? Apart from research buildings - given that mine aren't really helping me.
