Kalth'zar, I think I still have a lot of the stuff for "Gods & Generals" if you're planning to restart it. I'll look back through my vast archives (

) and see what I can find to help you.
Also, just some ideas to throw out there:
-Europe, following the Thirty Years War (start 1649?)
-Medieval Europe (1300 or 1400 look good), with a twist I've been putting some thought into: each player controls not just a nation, but also a dynastic family. Or, more accurately, mainly that dynastic family, which starts off ruling one particular kingdom, and acquires other territories through marriage, etc, in addition to the normal diplomacy and warfare of most NES's. A dynasty could start off ruling one nation and end up ruling an entirely different one. The downside is, it would require a lot of work, keeping track of family members and whatnot in addition to national stats, and having to forever be dealing with inheritances and succession conflicts.
-Napoleonic Europe
I'd like to see any of those, although of course I'm also glad to see someone starting up "Gods & Generals".
