Mouse control that is more precise than a joystick.
IDK what the fuck the left one is really for tho; a stick or even buttons would be just fine for movement. I am of the camp that thinks they’re uncomfortable and work less reliably than a joystick. Even a laptop trackpad is used with an index finger not normally a thumb and I never could get used to it. I hate my Steam controller and regret buying it.
It can be one button, or it can be 16 buttons or a radial menu or an axis or… I think it’s great especially for older PC games that weren’t designed with gamepads in mind.
I use laptop trackpads with my thumb all the time
