No matter what it is, I have complete faith in HTC that it will work, and add to the immersiveness of the game.
I said in an earlier thread that though a FPS might be too much, allowing troops to fight over towns (AI troops) would be very cool, and require multiple goon drops to take a field.
I would love to watch a nice firefight on the ground, and call in air support to strafe enemy troops. Hell, if you want them to realy go crazy, have elite troops that can be dropped anywhere on the map to attack Ground Vehicles. It would give the goon a whole new role in the game.
Just an idea.
