A few recommendations for AFK...
*
Fiasco -- This one see to be an overwhelming demand based on this thread... The dark humor, tension & improvisation for sense of story would make it very interesting to watch how it plays out.
*
Ticket to Ride -- Can't say no to train porn!
It's a great game for up to 5 people. Highly recommend getting the 1910 expansion for the larger cards & more tickets.
*
Plague & Pestilence -- This one might be harder to find, but this little gem has 2 parts where the ultimate goal is being the last person standing.
*
Mille Borne (aka Kilometre Borne) -- A little more pedestrian compared to other other options, but this old-school Parker Brothers classic that's pretty good in teams.
*
Atmosfear: The Harbingers -- While this one might be harder to stream due to some extra copyrighted material (the video that's included that serves as the timekeeper), but would be interesting to watch near Halloween for a relatively quick game (as it's only an hour long at most).
*
Clue (aka Cluedo) w/ special "Red Card" rules mod -- Clue may not be that interesting of a game, but I've created a special rules mod when adapting the game to BBS play known as "The Red Card". In this rules mod, 2 suspects are placed in the case file, but ONE of those characters / players are given the "Red Card" marking them as the murderer (which would only be shown at the end of the game)... giving the game two possible outcomes & adds a little extra twist. The drawback is that a non-player would have to set up the game due to special seeding requirements.
Will the murderer get caught red handed OR will somebody take the fall?
*
Betrayal at the House on the Hill -- Another one that's pretty good near Halloween, as it has a horror / suspense theme with an element of mystery since the game's goal isn't known until the second half when one player turns on the others.
*
Talisman -- An oldie, but still a pretty decent game in the RPG genre where everybody is questing to rule the world with the Crown of Command that's stashed within the center of the realms (or earth, if you want to consider that).
Just some thoughts.
