Can I make one suggestion regarding driving.
As a driver it’s fine the way it is… If you have a tank with manual gear you have to shift gears, and as soon as it’s done the automatic transmission for modern vehicles.
You have the throttle the way it is now making it an immersive experience.
I would also love to see a driving mode when you are controlling the vehicle as the Vehicle Commander.
I don’t know if you ever played Steel Beasts, and ArmA also has somewhat the same system.
Basicly you split the movement of the tank into 3 forward versions (Foreward slow, Normal Speed, and Fast) and a reverse speed (Maybe even two, Reverse slow and a fast reverse when under attack).
All you do is press forward once and it continues to move forward slow speed, press again and you go normal speed etc. Press S is stop and in steel beasts x is reverse.
This way you can concentrate on scanning the environment as a TC and not worry about driving.
