Each world will contain thousands of provinces to conquer, and thus hundreds of players in each world. So far the only interaction really spoken of between players is war. But war is really something that might not at all be a casual situation. With hundreds of players all fighting for survival it will be essential and so very much needed to form alliances and treaties of mutual protection with other players to ensure your own survival.
In most strategy games which go deeper than say, something as red alert, and become more like civilization or galciv. Diplomacy is very important and often in my opinion far too lacking. Because, what diplomatic options do we have in a game like Galciv. Not much, and by far not enough in my opinion. Simply the option to declare war, make peace, sign an alliance and the option to trade/give several sorts of things as money and resources. But for that game it might just be enough, there are in general not hundreds of races/players in that game. Or any game like that.
In situations where there are hundreds of different faction, like real life for example, there are an infinite number of diplomatic options to choose. Far to much to name. And a peace treaty is far more complicated than simply agreeing to not attack each other any more.
I feel we also need a nearly infinite number of diplomatic options to take with a game as Society. Now simply arranging things through chat channels doesn't really work. There would be no way to enforce diplomatics upon players and it would be terribly difficult to set up an interesting diplomatic situation.
What was on my thought was something as a "proposal creator" something you could make completely custom proposals with by putting in or leaving out elements and things so you could create your own customised proposal that would suit the situation you're in. Now this doesn't have to be a more complicated interface or whatever than in galciv/civ iv/or whatever. Just give it more options. And give something as a peace proposal more depth. By not making a button to insert a peace proposal. But several options so you can put together your own peace proposal just like you want it.
If we have something as this. We can take another step to create "regional" and "world" politics. In Galciv we have a UP council. Which gives a nice but not so very deep twist to the game. In a game like society, A large alliance of nations say, 10-20 (in a world of hundreds) could create their own council or region to protect mutual interests in protecting themselves from enemies and to protect internal interests of the nations in a region. Powerful alliances and regions could be formed that way. Also, if a world get's more developed and older a World Council might be erected in which every single nation may participate
This will also increase the say the player has in creating the world. Players will themselves define where the regions of a world lay. Players will be able to create their own laws inside a world.
Again, just a few of my thoughts how great the game of Society can become.
