So in the past couple months i have started multiple games with the following settings: immortal, large, ancient, abundant lux(where possible), no tech brokering, no events, conquest/tech victory only, earth or continents, no vassals.
In each game, i have played to at least around 1400AD, and in every single one, whether the early game had been good for me (where i was winning compared to nearby rivals) or not, I would eventually encounter one civ that had used the time better than all of us. This civ, the runaway AI ( seems independent of exactly what civ, i have seen mongols, arabs, poland, etc in this position), is suddenly somehow 9 techs higher than everyone. "Uh oh", i say to my self, and i imagine the other AI's mutter algorithmically to themselves, and try to speed up my own progress.
But how to speed up? I thought i was doing everything right? I had staffed libraries, I didn't cut down forests or jungles in preparation for universities, i even went after wonders that had effects on science, and tracked down any luxs that would help too. I tried hard to keep my happiness near 10, i took progress, and maybe authority (for science kills and happiness and the early settler). I tried to keep my net gold intake positive.
Meanwhile the Runaway AI has jumped from a lead of 9 to a lead of 13. WHAT?? Much gnashing of teeth and attempts to stall by way of alliance or UN sanctions.
The Runaway AI now has a lead of 20 and has turned hostile. Game over.
Seriously this happens every time.
So my question is this: why? how?
Also, how to deal with it
