REALLY, IF / REALLY, ALWAYS was put together with spreadsheets and scotch tape. I started working on it sporadically in early 2016, and finished in April 2018, in time to plant it in the Back Garden of the Spring Thing Festival of Interactive Fiction, and to have it published by the Orange Juice Public Library. This post summarizes the game’s development and construction.
First, a note on how the game works:
REALLY, IF / REALLY, ALWAYS is based on Bernie Cosell’s 1969 Lisp implementation of the ELIZA chat program originally written by Joseph Weizenbaum in 1966. The program simulates a dialogue with a psychotherapist, the “doctor,” by taking the user’s natural-language input, identifying keywords and/or sentence structures, then reflecting the statement back to the user according to rules associated with the identified keywords or structures. If, for example, the user typed, “It seems that you love me,” the doctor might respond, “What makes you think I love you?”
In the 1969 implementation of the program, there are approximately 250 potential sentences that the doctor can “say.” Some examples:
What might _____ represent?
Why do you remember _____ just now?
Let’s discuss further why your _____ _____.
Have you dreamt _____ before?
Please tell me more.
In each playthrough of REALLY, IF / REALLY, ALWAYS, every word in the 1969 doctor script is used in the potential “input” text exactly once. Keywords (such as remember, dream, love, etc.) are used any number of times. Continue reading “Making REALLY, IF / REALLY, ALWAYS”
