The Azurian
While the AI is much more challenging from the time I first made this thread there has been concerns about making later eras interesting. I am bumping this thread so we can discuss what can be done to make later eras interesting and unique.
Another issue may be keeping other civs that lag behind able to catch up. For instance we already have "tech diffusion" but I think we may need to boost it since C2C is a much different game than RoM/AND.
Likewise I think as the top civs reach some civs like Colonization and Globalization that tech should boost even the most backwards of civs. Because even today in the most primitive village in the remotest parts of the planet they have influences from the modern world. Be it owning a T-shirt or laptop but still living in a hut or yurt.
I am not saying all civs should be uplifted to the leading civs tech level but they should not live in a vacuum when it comes to techs either.
EDIT: I have also been thinking about revolutions. Especially since I had one in my recent game. I am thinking perhaps they should be more common. And those civs that do come out it probably should be stronger for it. Because what its doing is creating (for the most part) new civs at the same technological level as the nation they split off from. Thus becoming more powerful than struggling barbarian civ that just become a minor civ.
What controls tech diffusion in code. Alphabet, Printing Press, Globalization, Digitization should increase tech diffusion.
