Imagine you are playing a standard strategy game. Building bases, developing units, etc. Now slide your perspective down to the ground as if you are standing there as one of the units. The game has a new perspective, but the direction hasn’t. You are a field general, commanding the same strategies/deployments/etc as you did before, but now you are a part of it. Your commands need to go through other officers, and you can witness the deployments first hand. You have easy access to a map, that is rather similar to what you saw in the standard strategy games, but you point and give orders, and hope the officers know what they are doing. You yell out commands to the troops, and you can take part in it as well, like a war FPS.
I’ll add additional descriptions of how this will work, as I create them.
