Not very important, but I think it would be neat to add some more government types to the game. My Recommendations:
Corporatocracy
Confederacy / Confederation
Timocracy
Federation
Geniocracy
Cyberocracy
Isocracy
Necrocracy
Colonialism
Every time I try to change my domestic policy, I get an error that says "Your Nation title contains an inappropriate word." Not sure which word in my nation title is "inappropriate."
