From the Introduction: Scam discusses various aspects of scams, con games, and similar deceptions in the universe of Traveller. Nor does it limit the field of coverage to these criminal activities, though they are important to the supplement; the systems presented in Scam are intended to permit player-characters to attempt a wide variety of deceptions, falsehoods, or impersonations as a part of their ordinary adventuring activities. Thus the material is in no way solely concerned with enabling characters to make money off of their gullible companions. All areas of interpersonal relations which are likely to arise in a given adventure or campaign may be handled by using this supplement.
