This sounds very similar to something that Hideo Kojima mentioned wanting to do for a PC game:
"So maybe when you put it [the game] in your disk drive and you're playing for about fifteen minutes, the heat from the disk drive interacts with that chemical and creates a certain smell. It smells like blood or something like that," he said through a translator. "And when you pull it out you see like a dying message on the disk. That was actually an idea I had for the original Snatcher but unfortunately I got yelled at for it and they didn't let me do it."
