I'm gonna give up on the improbable mod, I need more experience with modding and unit creation before I can do it. However, I have another idea. I want to make a mod that focuses on the second half of the game, since most of the units are there, and also most of the buildings. So, here's my idea for a tech tree. this age here, the Early Industrial, represents roughly 1800-1880. Please tell me any inconsistencies, thigns that need to be added, things that don't etc.
Just worry about the tech tree now, I'll figure other things out later, so don't ask me about civs, maps, etc.

Creative...unique even. :goodjob:

If you spilt the game up in to four era; Industrial Revolution (1775-1850), Age of Empires (1850-1940), Nuclear Age (1940-70) and Space Age (1970-2020). This would allow for changes in game play from muskets to modern weapons.

1st Era - 1800 - 1880 - Civil War and Industry
2nd Era - 1880 - 1950 - World Wars
3rd Era - 1950 - 1980 - Cold War
4th Era - 1950 - 2015 - Today
