If anyone that played IG in 2005 remember that the IG Diplomacy actually had some really good options..for a game in 18th-19th Centuries and also one in 2005, no matter the crapiness of the game, it had really good ideas that could be implemented into NTW:
A few Examples(If my memory serves me... I could use help if you remember them)
-Coalition(Able to make one with various countries)
-Liberate A Country(?)(Like if Russia takes Poland or Moldavia.. You as Austria or Prussia etc could take it back and give the Poles a country back but with conditions..An Alliance, Trade, etc.
Thats all I can remember right now...
Anymore are welcome!
