I dunno, RPG players? Don't you wander around RPGs beating the X button just in case something secret or hidden shows up? Didn't you ever play Final Fantasy VI?
Not really. I had the emualater that just disable the black on the screen so I saw all the hidden items and such for VI. Though you would never hit the X button at the end of the game for fear of missing a sceen or important dialog. the only reason I found if was because I happened to drop the controler and it happend to land on the X button at the right time
