I only call it War because I couldn't think of any thing better.
The game mode would be two factions and netural. Factions being Marines vs Insurgency, the neutral would have to build towns and gather supplies to survive, they could make shops to trade with the marines, and use some sort of tool to name there town. The town would then be able to become an Insurgent town, when it is insurgents would get a health bonus. The marines would have to try to take over the town using a seige like system (TDM), once it is taken over they could choose to take over the town or make it netural. The marines would be able to deliver supplies such as grain,water, and other things, this would give them Command points, command points would eb sued to win the game mode. Team that reaches 300 command points wins. To get transportation, said team would have too make a building on a certain size baseplate with a certain hight to get them, you would then have to get command points to spawn them. You would also be able to get air-strikes as marines to do this you would have to make a radio tower, and consoles in a building, these consoles would also cost command points. To balance it the consoles could be destroyed by an attack by the insurgents.
This was just a crazy idea I had .
TL;DR
Don't be lazy read it.
