I would like to be able to base air units in allied city states. This would add more depth and realism to gameplay. In real life an allied city state (basically a friendly, smaller, subservient civilization) would allow an allied major civilization to base air units in their territory.
This is very imprtant because you can be allied with a city state that is very far away. You may be using that city state as a launchpad to launch an attack on another civ. Its easy to move land units into posotion, but the enemy air force may annialate your ground forces. I know you can use carriers, but realistically, an allied city state would let you use their city as a base too. This is much easier than using carriers, especially if the city state is not right on the coast. If the enemy has a strong airforce it would be nice to be able to base fighters in the city state to intercept, and bombers to soften up enemy units/cities. Also, you may not even be attacking another civ, but just using your airforce to protect the allied city state from another civ.
Also, friendly civs should allow basing of air units if there is an open borders agreement, especially if you and the friendly civ are fighting a common enemy. In real life this would happen. For example, in WWII Americam planes were based in Britain. The war may have turned out differently if this did not happen.
Maybe for city states and other civs there could be a limit per city so it's not out of balance. Maybe 3 units per city. Or maybe there is no limit, but you have to pay a certain amount of gold per tun for every unit that is based in a city that is not yours, and the gold would go to the civ that the unit is based in. But realistically, if an allied civ or city state is fighting for survival, they would not charge you to come in and help, they would welcome it.
