Only the most generous of spirits could call this interactive fiction. I’m not one of those. I call it a random text generator, which only responds to two (or maybe three) commands.
The text it generates, in mock-medieval style, is one account after another of the adventures of “Sir Algebrah”, who wanders around killing some things and having sex with other things. That’s why the two commands RPG responds to are SLAY and LAY. If you enter any other command, or indeed no command at all, the program interprets your input as a “battle-cry” and then proceeds to print whatever it wants to.
It’s a reasonable, though wafer-thin, parody of fantasy CRPGs, and as such it’s entertaining for about 60 to 90 seconds. After that, it’s dull, and at no point is it any sort of interactive fiction.
