Retropie 2 Player Arcade Fight Stick Shell, Need Opinions

[shanet94]

We are having a 2 player arcade fight stick made to house the raspberry pi. The shell will be built around the pi so it will be a professional looking case. We have all the inside mapped out as far as location of all the needed hardware. What we need advise on is buttons. Most arcade builds I have seen run the following:

Joy Stick
Eight buttons (B A X Y Right Shoulder Left Shoulder Start Select)

Will that cover the majority of the games that RetroPie is capable of running or do we need more?

Thanks for your opinions! Very excited about this project.

8 buttons is more than enough for retrogaming and emulation. The number of games needing more buttons is ridiculous... even 6 should be enough.
