I ask you, what, exactly, is the difference between a "keyboard" and a "controller"? These are terms people just use because people want to categorize everything based on superficial differences, generally so that one can feel superior to another. People, please reject those outdated cultural prejudice.

If we dont see bad or good around us what comes of us?
but anywho a controller is waaay better then keyboard imagine playing FPS games with a keyboard, errh not going to happen im guessing. Keyboard + mouse = Controller buut just keyboard going solo :/ yea i dont think its anywhere close to a controller. Props to those Keyboard warriors, its a hard task and you could potentially be better so invest in a controller!
But if u have a controller and only use block to maneuver your camera around like keyboard warriors do, then yeah keep practicing on using analog joysticks.
