Hmm, I didn't actually count, I just assumed your count was the total. I haven't read Meaning of Liff so I guess I'm at 9. I played almost all of the Hitchhiker's Guide to the Galaxy Infocom game, though (I gave up when I realized none of my saved games included the pocket fluff). But only the beginnings of Bureaucracy and Starship Titanic. (I just started reading the latter novel last night, but that's by Terry Jones.)
