Ok I got this idea from browsing mods for civ: be. I think orbital layer is a good concept but really doesn't have a whole lot to it. I think the orbital layer could be utilized more and have a greater impact on the game if special units were added to the game that could operate in the orbital layer. I realize this could be an OP element in the game but it would greatly increase the need for for cities to have good or decent anti-orbital range attack. I realize that the harmony affinity has a unit like this but I think it would greatly increase the strategic aspect of warfare. I realize there are attack satellites you can build but what if you could build some type of space ships that could bombard the surface and be able to help with attacks and not just defense. Yes you could destroy your orbital attack satellites and move them but that takes up production and time. I would like to two or three types of orbital units 1. strictly for bombardment 2. strictly for attacking other orbital units 3. a hybrid that can do both but isn't quite as strong for either but could adapt through infinities one way or the other. I realize that could begin to take away from a ground war but cities are all on the ground so you would still have to have an army. A way to limit these units but still allow them to have an effect on the game would be to put them in later game techs, increase how much production it takes to create these new orbital units (don't increase satellite production I think that is fine),and make them use strategic resources (Titanium, Geothermal, and Petroleum). I think that would be fairly balanced. Anyways I know rising tides is almost out but maybe for the next dlc Firaxis could move from the water to space. Anyways I would love some feed back guys! Oh and if you have any other ideas that would be great!
