I was playing a game recently and thought that the control scheme (with some modifications) would be good for Big Ambitions.
The game: Good Company, A Corporate Machinery Simulator.
Left Click - Move/menu interact > I would modify this to Move/any interactions
Right Click + Drag - Free Camera
Right click - Environment Interact > Would modify this to 90 degree turn
WASD - Free movement
Would add QE for free rotation, since the Good Company game doesn’t have camera rotation, and it would be convenient.
