Amazing Engine was a series of role-playing game books that were published by TSR, Inc. from 1993 until 1994. Each publication employed the same minimalist generic rules, as described in the Amazing Engine System Guide, but each world book had an entirely different setting or genre. David "Zeb" Cook was credited with the design of the game rules.
In Amazing Engine, player characters are generated with a set of four core statistics. The core stats were intended to be migrated from book to book, keeping a general character design concept. These stats were then used to build random ability scores, basic characteristics, and skills. The skills have prerequisites which must first be learned. Skill checks are made using percentile dice.
