Alternity was a science fictionrole-playing game (RPG) published by TSR in 1998. It was discontinued in 2000. It retains a small but devoted fanbase.
System
Like the d20 system, the most rolled die in the game was the d20, but instead of applying set modifiers or difficulties to the rolls a second die was rolled and added to or subtracted from the d20 roll and the result was compared to a character's skill score. Designed to be a generic rule set around which a campaign world could be built, it was not very heavily marketed and suffered from mediocre sales which, along with increased focus on the d20 system, led to the discontinunation of the game in 2000.
Characters were created with a point-based system, and could be either humans, aliens of one of several races presented in the core books, mutants, or aliens created by the GM. Classes were replaced by professions, which dictated which skills and abilities were cheaper for any given hero to get, though a few skills (in particular, psionics) were restricted to specific professions.
