Well, apart from redhead's cassette tape (I don't remember his name but the sassy one who's going out with the big dumb one), all the tapes are actually accounted for ; tho from what I understand there should be more cassette tapes than players (since best friend guy had two - I really suck at remembering names)
Wow this got somehow managed to get even darker. The fact that all of them were originally players who eventually gave up to become npcs... That means there are way more cassette tapes (for each player).
