Zork II. The Wizard appears at random intervals, points his wand at you, and casts spells on you, all of which start with the letter "F": fall fantasize fear feeble fence ferment fierce filch fireproof float freeze fumble If your lamp burns out, he may cast: fluoresce And, if you try to do bad things to the princess, he will appear and cast: fry Those all do fairly obvious things. Fantasize is particularly amusing; until it wears off you are told that you see various unusual things such as a pot of gold, and a grue (which are never seen by the light of day).
