Megaversal system

The Megaversal system, sometimes known as the Palladium system, is a set of mechanics specifically employed in most role-playing games published by Palladium Books, with the exception of Recon. It uses dice for roll-under percentile skill checks, roll-high combat checks and saving throws, and determination of damage (i.e. Mega Damage is to M.D.C. what "damage" is to S.D.C. ) sustained in melee encounters by which a character's Hit Points, Structural Damage Capacity (S.D.C.), or Mega-Damage Capacity (M.D.C.) is reduced accordingly.

Shannon Appelcline, in his book Designers & Dragons, states that the Megaversal system was a revamp of Palladium's AD&D-derived game system: "It was one part highly traditional – with its character classes, experience points and levels – and one part arcane – with its abbreviations like OCCs, RCCs, PCCs, PPE, SDC and MDC."

Certain aspects of character creation vary across series. Depending upon the game, players may or may not need to select a race; for instance, it is assumed that characters in Ninjas & Superspies are human, while in Palladium Fantasy they very often are not. Nonetheless, all games share the same eight randomly generated attributes:

For humans, most of these statistics are determined by a roll of three six-sided dice, whereas other species' attributes are determined more or less depending on how they compare to the baseline human standard.

Other statistics that may be used are:

The characters' race and attributes – not to mention the game itself – impact their selection of character classes:

Depending upon the game, skills can come either from the character's O.C.C. and a related list, or from the character's educational or occupational background. Games set on modern Earth tend to favor the second; all others favor the first. O.C.C.s tend to be more specific than character classes in other games, with a wide range of O.C.C.s in a given profession, such as six or seven specialized mecha pilot classes in Rifts rather than a single "Robot/Power Armor Pilot" class.
