I played MMOs for years using the Keyboard and Mouse, then when my computer pulled stupid I had to go to using the controller on my PS3. It was a learning curve, but eventually, I got used to it, and It's SO MUCH BETTER. Especially for me, when I get excited I shake really hardcore and then can no longer hit keys on the keyboard. But with a controller, the shaking doesn't even matter. After I got a new computer, I tried to go back to keyboard and mouse and I couldn't. Nothing made sense anymore. I couldn't do it, it was so bad. So I got myself a driver for my controller now I use it both on PS3 and computer and everything is good forever XD
