So, simple question: When you go for an ideology in Brave New World, do you prefer to go the three factories route, or do you get one by hitting the Modern Era? I ask because in my recent game I was doing the One City Challenge, and couldn't get enough factories to build it. So instead I rushed into the Modern Era; Scientific Theory -> Electricity -> Radio. With the use of a Great Scientist and Oxford University, I was in the Industrial Era for a grand total of 7 whole turns. I finished the Industrial Era without ever industrializing. Though, under normal circumstances (Non-OCC) I prefer to go with the factories. After all, coal, factories, and gatling guns are pretty powerful, so there is some major incentive to use Industrialization as the intro tech for the Industrial Era.
