I would like a game where war truly is the LAST thing that will happend after MASSIVE diplomacy failed..
For this example I use Race A and Race B (surprised?)
A has 4 planets and B has 5. A feels that it wants to expand to a new system and colonizes a planet close to B:s space, this planet is also supposed to be a base spying on B, but that is a secret.
(This exchange of diplomacy takes place over a number of turns, maybe around 10-15..)
B does not like A:s decision and confronts them and says: "The system X you recently colonized is very close to our borders, what are your intentions?"
A responds: "Its merely a new planet, no military outpost or spy base"
B: "I see, well just to make sure we demand that you keep this new planet military free for X number of years"
A: "Im sorry, but that would severly compromise our security, so we cannot do that"
B: "I see, well perhaps you would allow us to have complete insight on what is happening on the planet so that we can determin for ourself?"
A: "That is not an option either Im afraid"
B: "Well, it seems that you indeed are hiding something"
A: "No, we are not, itsmerely a planet"
B: Well, then we cannot allow you to keep this planet, if you do not comply you will force us into war"
A who do not wish war, but do not want B to detect the spy base tries to avoid war.
A: "Well, maybe you could have limited insight on the planet."
B: "That is not an option, then you could easily hide something from us"
A: "Well thats as far as we can go im afraid"
B: "Then you leave us no choice"
Declaration of war is issued and a couple of turns later the first battle takes place.
The war may take all from 100 years to merely 1 year, it depends on how well it goes for one of the sides. The length of the war also affects the amount of "hate" that will exist between the races after the war.
After the war has ended, due to some extensive diplomacy as well, Race A and B are no longer very good friend, they cannot exchange any type of "friendly" trade (tech for example" for at least 20 years, normal trade can start after about 10 years, but the history of the 2 races till always remember this war and not until about 50-60 years later they can have a normal relationship, if the relation scale is 1 to 10 were 10 is as close as you can be, the two races cannot come higher than 5 (neutral) during the first 10 years, 6 after another 10 years and 7 after yet another 10 and so on.. Trade is also penalized the same way, as pirates from the two races constantly attacks the other race trade ships due to the hatred from the war.
It just some thoughts from me, if its possible It would be nice to have even MORE diplomacy LOL
