Actually, no I'm a rightie but that's why it's the way it is. I suck with any sort of motor skill function on my left hand, but I can pound buttons with it :^)
My right hand does the fine motor skill work, so I use the joystick that way. I am thinking of building another panel to accomodate visitors who prefer the other style. My plan is to probably have 2 control panels like the one currently shown, 1 for lefties and the other for righties, plus a dedicated rotary stick panel, a dedicated 4 way panel and a dedicated, 45-degree QBert panel. That should cover all my bases. Of course, I have to get a lightgun too, but I won't do that until I decide of I'm gonna switch to a VGA Arcade Monitor instead of the TV. If I do, the TV will migrate to the living room for use with the XBox, Gamecube, PS2 and Dreamcast.
