We do not have a thread for improvements yet so let's get one started
The first Improvement change I am considering is Strongholds having an effect on "sphere of influence". Sphere of Influence is just another name for Culture really, but I kinda like it over Culture as two Civs can have basically the same Culture, but different Spheres of Influence, however it is all basically your Borders. Anyway, to help counter other Civs from encroaching on your Borders you can build Strongholds. Strongholds will exert your Sphere of Influence to the tiles around them.
Perhaps this effect only occurs while the Stronghold is Manned, connected by Road, or perhaps under certain Civics, or all of the above. Civics can give bonuses to this effect. Perhaps you would need to consume Yields in the Stronghold to exert Influence.
The amount of Influence would be a calculation of your Culture totals that exists around the Stronghold plot. So, if a Stronghold on the edge of your borders is only connected to three tiles, those three tiles will be the factors for the amount of Influence the Stronghold welds. The more Tiles around a Stronghold the bigger the Influence.
This would be another way to Expand your Borders as well as acquire Vassals. Building Strongholds outside your Borders can still be a way to expand Borders. Their Influence would be diminished however, they could still have an effect depending on plot distance from your Capitol city or borders perhaps. This distance could be calculated at when the Stronghold is created to optimize cpu time. Strongholds adjacent to a Minor Civ city could get an increase from Missions and Trading Post established in the city.
Any thoughts on this or other Improvements?
