Controllers for video games are essential to the experience. A cheap controller can lead to frustration during a session. It can also be the difference between victory and failure, especially in the competitive world of gaming. With that in mind, Mad Catz has come up with the Mad Catz Major League Gaming - Pro Circuit Controller. The controller is touted as being highly customizable to the player, so I took the Xbox 360 version for a spin to check out the claim.
