Realistic RP Based Strategy Game

I have been playing a decent amount of RP recently and it made me get to thinkIng about what if there was a game in similar fashion to AtWar, but where it is almost totally realistic in the facts of that the RP that you are used to pretending with the other players becomes a reality that the game accepts by giving you many different choices of types of government, economy, foreign relations, etc. and with these the game creates a realistic tie between them and how they would effect your country and the rest of the world in all different ways. I was recently inspired when bringing this idea of mine up in a RP game and receiving a decent amount of excitement and want for something of the sort that I decided to begin making this game a true reality.
I would love and will take into account any and all suggestions for this game and the aspects of it. I also will answer any and all questions about it to the best of my ability as well as I encourage any and all questions to be asked.
