Icom's Macventure games (Deja Vu, Deja Vu II, Shadowgate, Uninvited).
Unfortunately, if you want to play the superior versions of the games, you'll need to figure out how to get them running on an old 2-color Macintosh Pro, or I guess the Apple ][GS versions aren't too shabby if you have to have color graphics.
