The very first one is set in 1900 and can be found . The same guy (the creator of the system) did a 1920 one as well, . Most recently, he did a 1778 one, . IIRC, there's a Cold War one around here somewhere as well, but I don't think I'd trust that game since we apparently can't go one turn without a World War. :P
Those certainly sound fun. I'd love an 1836 one, though. THAT would be fun for someone like me... (If we do it, dibs on Texas!)
