The "main" control pad doesn't seem like necessarily the most important thing: the most important thing is that on the back of the controller, there's a whole row of ports that you can use to plug in standard assitive devices into (buttons, pedals, sticks, whatever) to act as controller inputs. The idea is that it should be as flexible as possible to adapt to everyone's needs. I'm sure you would be able to find a solution for the games you want to play.
