I am a xbox player who moved to the pc version for more content. After a couple of days i thought my hands would fall off. the mouse keyboard is not an ergonomic xbox controller and i refused to let my hands dictate my amount of play time. As in all things google saved the day with this josh carrier dude. He has this mincontrol program he designed that allows you to use a "corded" Xbox controller. the past few months have been so-so with it because it's not like the xbox version. It was choppy and too slow, it sucked but it worked.
Today it got an update. Whoa, what an improvement. It's better than the xbox version with it's sensitivity adjustability and button mapping you can get an almost mouse precision. I bow down to you josh carrier who has outperformed microsoft, because you have made my minecraft dreams come true.
All you need is a $20 controller and the free program If you want an ergonomic feel to your minecraft. Check out Minecontrol, You'll be happy you did!
