Whenever I get a new (used) game, I always thumb through the manual and see if the high-score page has been filled out, or if there are sticky notes with codes on them. So I was wondering, how do you feel towards these sorts of discoveries?
To a certain extent, I get a kick out of it, even if the original instructions have been written on. To me, it gives the game a touch of personality, evidence that it was appreciated by it's former owner.
Also, what's the strangest thing you've discovered inside the case/instructions/cart of a used game?
