i was thinking of something like a psp joystick or a blackberry trackball (theyre hall effect and sparkfun sells em). my idea is to put the thumbstick/mouse where the thumb button/hat would be, but also include a hat switch above it as well as a trim wheel to complete the cluster. high up buttons and switches on joysticks annoy me to no end. i want to bring them down so my thumb doesnt go numb during a game of mwll because of all the camera zooming you need to do. i plan to clip the whole top of of the joystick, having it go no higher than the trigger assembly. it means less space for buttons, but theres still room for pinkie switches, possibly a dual or staged trigger, maybe an analog trigger (variable speed gatling guns!), a rocker switch just above the trigger.
