I was thinking on making just like embryodead said, a Renaissance and finishing around the Victorian Age, but i think you beat me to the idea. Just a couple of thing:
1. EB and Yoda Power did a lot of reasearch to put together the rules and flavors of MEM. If you want to put a team for a mod, you need to get around how to put differents process and ideas into Civilization, how to get around the editor and the rules alowing not only to be historically similar, but also fun to play.
2. You will need to have paitience, not only with the people working with you, but also with graphic makers and unit makers, and also be sure that you will be investing time on this.
3. More expirienced modders can help you telling you which tools are better for editting, adding stuff, etc, I think those two (ED and YP) can tip you on making amazing mods.
4. you can count me in.
the first thing that I think on modmaking is what to play, where to play and who to play: We now that is a Europian Mod, but maps can vary: You can create a map of your own for this. Also, you need to limit the mod: Is you play 4 centuries of europian history (15 to 19) you need to divided it in 4 eras: Renaissance, Age of Exploration, Age of Nationalism, Age of Imperialism. Everyone should take care of around 120 years. Also, you need to choose to play on a full map or a naked map.
