If all participants used the same peripherals and were only able to tweak their settings via the GUI. How much of an impact would this have on their game? Would players styles be noticeably different or would this experiment just show how it really is all in your mind and what you're comfortable with.

Also, I think it would be cool if we had a top down camera POV that focused on each players mouse movements that could later on be embedded with VODs from the stream.
