There are 4 face buttons on any fighter on steam, since they're all ported. So N, S, E, W on the right track pad are face button. Then you have like 14 other buttons around the controller. For fighters, you really only need 2 of the bumpers: 3 strong attacks in one button and maybe a throw button. As far as directionals, that's the easiest part since it mimics the joystick on an arcade. Shoryuken? Make a Z. Hadoken? Slide your finger down, hold and track it to the right. The rest are just extensions of that. Now, you have stupid games like Mortal Kombat where a fight is really just you memorizing a cookie cutter combo you saw on youtube, but I'm sure it'd work equally as well using the controller.
