^About the stick clicks: since we talked so much of FPS games, they are essential for example in KZ2's default control scheme as they are bound to sprint and ironsight toggle. KZ2 uses all 6 of those buttons, by the way, so that you only have to leave the right analog stick for actions that stop your aiming anyway (reload, change weapon, jump, use).
Beside this particular example though, I think every PS3 game I own uses them somehow.
Besides, if you bring up the nunchaku's accelerometers (the wiimote is supposedly being used as a pointer instead of one of the sticks, so you can't consider its motion sensing at the same time, same as face buttons on DA) i can bring up the sixxaxis accelerometers too :)
Oh, and to top your dismissal of the analog triggers: actually on the PS3/PS2 - not sure about the 360 - all 4 face buttons are also analogic (and yes, there are games who use half-presses, such as MGS3/4)
