I went over Age of Man with Fantasy races that was uploaded to Steam and i managed to rework it so that it works with current version of the game. Steam version lacked many features such as Scouts.
I also removed all the custom buildings because they were wonky and offset seemed wrong. I only kept reactions for bulk bricks and bulk charcoal. Humans also can't make steel, and i wanted to keep that. You can smelt steel items you get from Dwarven caravans though. This is a tradeoff for being able to drink water and live anywhere without worrying about Aquifers.
I strongly advise anyone playing this mod to turn off the weather. Rain is by far the worst mood killer for your humans, even though they all have loves outdoors by default.
