I think a cross between #1 and #3 is easily the lion's share of viewership, especially if the game is difficult and almost antagonistic toward the player. I'm reminded of the Youtube videos posted some years ago by ProtonJon of his Super Mario World ROM hack play-throughs. I'd never personally play them, but it's easy to get an almost schadenfreude-level of enjoyment out of watching someone else suffer through a game that's extremely punishing. The same easily applies to other games that most people wouldn't ordinarily play for a variety of reasons (too old, as in your example, or perhaps too frightening e.g. Amnesia--that one made the hair on my neck stand up).
