It seems that as the years go by, more and more games have turned to the analog sticks for functions that, a console generation or two ago, were mapped to buttons. In most cases, this change has been for the better, offering gamers a higher degree of control. MX vs. ATV Reflex changes up the franchise's long-stagnant controls by introducing Rider Reflex, which provides a much more logical and natural control scheme. As usual, the right trigger and left trigger are the gas and brake, respectively, and steering is controlled by the left stick. But the right stick gives you complete control over your rider's body, so it can be controlled independently of your vehicle.
Rider Reflex allows you to take tighter corners, jump higher, and avoid crashes. With the right stick, you can shift your rider's weight to lean left or right, which makes a huge difference in how sharp a turn is. And while preloading jumps used to be controlled by holding down a button, you now pull the stick down on the way up a ramp and flick upward to launch yourself into the air. It's a much more intuitive and fluid control scheme, and it really makes you wonder why this hasn't been implemented before. There's no going back from this -- from here on, it should be the standard control scheme for these kinds of games.
