I noticed Alex of Macedon built tons of naval units, but seems to me he does not know how to use them... He sent 3-4 submarines to the pass controlled by my 2 destroyers which made short work of them... I also noticed he had at least 7-8 obsolete naval units... Had those been upgraded my naval invasion would have failed for sure... He had the second largest empire, most advanced tech and probably the cash to pay for those upgrades...
And in a war infested king post patch game, there are surprisingly a lot of uncolonized land, even on our 2 continents... That is a first time for me... even a patch of land that has all 4 whale resources has no cities, and its connected to the inca.
