Hey!
I tried a whole game with your mod combined with the City-State Diplomacy mod and it works really great! I performed a military victory with Russia, on Prince with Terra map. This was a really long game (maybe 15 hours) and I reach only the industrial era (standard size).
I noticed a bug (or maybe it is not one) with Russia: when you are building a... (damned I forgot the name of the builing) the one that is using Iron to enhance production
like the forge, more than one iron is used per building, this is due to the bonus of Russia to get double iron. Nevertheless, shouldn't it consume only one resource? This is not a big deal because you can find a LOT of iron in this mod.
Another point: the AI didn't at all tried to reach the new continent in the Terra map, even at the end of industrial era (this is when I won).
I recommand a lot to play this mod combined with the City-State Diplomacy mod, because it enhances the city-state strategy and, when you declare a war, you declare it many times to numerous city-states. It is also a good way to spend the large amount of money you get during the game (the minimum to spend on each city-state is 2000 gold)
Why not combining your mod with the DonMartyMod?? Just to render the game even longer with early era?
I'm expecting a new update soon, I have great hopes with your mod, keep on!
