Trust And Betrayal

Trust & Betrayal: The Legacy of Siboot, often abbreviated simply to Siboot, was a game designed and programmed by Chris Crawford and published by Mindscape in 1987.

"Siboot", the name of a character in a novella included in the manual, is a reversal of the syllables of "Bootsie", a cat which Crawford had. Bootsie had to be euthanized due to an irreparable injury to his jaw. Crawford suffered much grief while contemplating that he was unable to talk to Bootsie in order to try to comfort him, before he had to be put down. One day while pondering this, Crawford had a flash of insight: his next game would be Talk to the Animals, which evolved into the very different Trust & Betrayal.

The final design can be summarized as follows: The player, a creature named Vetvel, must compete with six other acolytes (each a different alien species) for the Shepherdship. Each of these characters has a distinct personality. Each morning, the acolytes wake up knowing one of each of the three "auras" the others possess. They must trade knowledge with each other in order to try to gain enough knowledge for the "mind combat" that takes place every night, which is basically a fancy Rock, Paper, Scissors game that depends on the aura counts for the players involved. The game is won when a player gets eight auras in all three categories. However, in giving away somebody's aura count, the player betrays that person, which angers them and may make them less likely to trade aura counts with the player. Therefore, a player has to know whom to trust and whom to betray, hence the title: Trust & Betrayal.

The game had several unconventional features. For instance, it featured an inverse parser, a method for constructing sentences out of words while only presenting words that make sense for the given context. It also placed some emphasis on facial expressions as a visual form of feedback. It even had a primitive form of tooltips: if the player clicks and holds the mouse button on an icon (the game's abstraction of a word), one can see its meaning. The number of icons is small enough, and the pictures intuitive enough, that they can quickly be committed to memory. It also featured "interstitial stories", interludes that appear through the game that present the user with one of several choices, some of which may affect the game. For instance, to use an actual example from the game, if game designer Chris Crawford appears and lectures the player, and the player responds "Go to hell, Crawford!", then he or she loses some favor among the other characters, making the game harder to win.

Siboot didn't hold up very well in the marketplace and did not recoup its investment. It sold 5,000 units on the Apple Macintosh. A preliminary IBM PC port was made but never finished; however, it can be found on the web, although it has some problems (for instance, the random number generator is not initialized properly).
