I just built 3GD in my cap, took less than 20 turns on Epic, I thought that was acceptable. Something weird has happened. I have been behind in tech throught most of the game, Gilgamesh had Infantry before me, for example and he also dominated the score board for a long time. But somehow... he now needs 96 turns to research plastics. How could he possibly fall that far behind? I now have like 6+ techs he doesn't have and all he has is Fascism. His vassal, 3-city-Rags is WAY faster in tech than Gilgamesh who has a really large empire.
