For me, literally game changing item is a game controller. For the games with native controller support it is awesome. Its easier and more confortable than mouse and keyboard. Of course it is not comparable with mouse and keyboard, especially in games heavily relied on mouse, but for anything else, on my opinion, it is a better option. My controller is quite cheap, but works well. I bought a controller to see what it is and how different it is for gaming, compared to mouse and keyboard. At first it was difficult, as i did not have an experience with controller, but now i enjoy it.

Fortunally for me, it did not take a lot of time to get it.
