Started an all standard renaissance game, I was also unable to see the new boats on non resource tiles. The research production sink needs to be nerfed, I almost quadrupled my science when my top production city went research. 5% or maybe even less would be good. Starting gold for that era is a bit obscene. I spent fairly slowly, but was still able to rule all demographics with over half of my original 100000(or was it a million?) still banked. That starting bank was enough for a dozens of settlers, or hundreds of workers, or a combination. Gold and production seem much more balanced overall. Though I think food still needs some work to slow growth slightly. Did you mean to have both the windmill and the mill(which pictures a windmill)? For unit gold maintenance, I think 10 gold per column from agriculture would fit. So warrior would be 5 since it's available at start, and every other military unit would be a multiple of ten, and late units would cost over 100 each.
