The versatile controller
When most people start their adventure into the world of flight simulation, unless they’re considering a career in aviation, they don’t normally consider the hardware needed to control the aircraft. Some will master the keyboard and mouse, which I would say is the worst possible method and some will invest in a cheap joystick, or possibly an Xbox controller, both of which in my opinion are a step up from the first option.
Of course, once they get hooked it becomes more serious. At this point, pilots start to invest in the hardware (and software) that makes the simulation experience more realistic. Once again, this can add a different satisfaction derived from better mastery of the aircraft. For this, you need a decent yoke and possibly a set of rudder pedals too.
