I would like to see a mod centering around warfare. Occupying land with units: for instance I think it should be possible for units to occupy land without capturing a city. making it possible to advance into enemy lands and capture recourses for instance. this of course could be limited so that you cannot occupy the lands 1 or maybe 2 tiles near a city without occupying the city itself. maybe?... Units run obsolete: I find it very redicilous when a unit that is highly technologically superior to another unit has to put up a fight or is hurt by a unit that in real life would not stand a chance, literally. for instance riflemen vs a jetfighter? I can accept that the unit survives the attack but that the jetfighter is damaged would be impossible in a real life scenario thus makes the game less realistic. there could be a number of examples but i dont wanna mumble on... maybe something that could be fixed? Emerging citystates: I think it would be very interesting to enable the emergence of citystates after concuest. in civ5 we now have the choise to either annex a concuerd city or make it a puppet, or if one wish to, destroy. I really like the concept of the puppetstates since many empires governed their concuerd lands this way but to contradiction to real life many of these puppetstates would revolt against their concuerer occasianolly. for instance there were three major rebellions in babylon against the achamenedic persian empire. so I think it would add a little exitment to the game if puppetstates occasionally could revolt forming independent citystates if ones empire would be (for instance) unhappy for a time. maybe somthing? I really like the new concept of citystates since it brings a very known fact to the game, that the world does not soly consist of a few large empires but also a large number of smaller ones. to enable smaller empires to emerge from larger ones brings another known fact to the game and that would be that a large empire wich is not well gouverned falls into smaller empires and thus sieze to exist. now I have no idea how this modding stuff works so I have no idea how hard this would be to do but perhaps it does not sound to booring and perhaps it cought someones interest.
