3. The Mako controls much better.

Simply put, the gamepad necessitated the basic "Mako follows where the camera is pointed at" control scheme for the Xbox 360 version. The Mako felt just fine when you were driving it in a straight line with the camera positioned directly behind it-—yet when you tried advanced tactics like circling around a stationary enemy, or just plain looking around, the controls just felt weird. Now, the controls are camera-independent. Meaning, by default, W always zips forward, S always goes in reverse, and A and D always turn. It sounds a bit minor in text, but when it comes time to circle strafe a giant thresher maw, it's a damn nice change; in fact, BioWare somewhat retuned the thresher maws because the new Mako controls made them too easy to take down.
