Are there any games out there that use more than 6 buttons? I'm sure there are, but I'm working on my CP and I'm trying to decide how to place all my buttons. I have 19 buttons to work with. Right now, I'm planning 6 player buttons, coin, and start for each player = 16 buttons so far. Then and Esc, Pause, and a Shift for Admin buttons.
Back to the original question, what games use more than those 6 buttons? This is kind of a cost vs. reward type decision.
