Others I own, but (as usual) haven't played:
Don't Rest Your Head: Chronic insomnia has led you to the Mad City, where you must tap your exhaustion and madness to elude clockwork policemen and bad-news paperboys ... but go too far, and you'll become permanently unhinged ... or pass out as the horrors of the Mad City close in on you.
The Shab-Al-Hiri Roach: A GM-less scenario in a Lovecraftian college which asks if you're willing to abandon your will to an ancient roach god ... even if it gets you tenure.
"On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
- Charles Babbage (1791 - 1871)
