Alternity
In 1998, after TSR had been bought out by WotC, but before it was dropped as a separate brand, it released a generic rules set for science fiction role playing game. It was written by Bill Slavicsek and Richard Baker. Characters would be created by a points system for six statistics (Strength, Dexterity, Constitution, Intelligence, Will, and Personality) and take on one of five classes (Combat Specialist, Tech Operator, Free Agent, Diplomat, and Mindwalker). Using a dual dice mechanic of rolling a control die (d20) and situation dice (such as d4) for resolving tasks but the dice size and number rolled could change due to circumstantial modifiers. The aim being to succeed by roll low under a target number (such as a skill) then working out what degree of success or failure occurred.
Despite being a nicely-illustrated book, having good reviews and a well presented rule book, it had little in the way of actual sales. There were a few campaign settings sold for it, notably a pen and paper version of Blizzard's PC game Starcraft. The product line was discontinued but settings such as Dark Matter survived into D20 Modern. Wizards of the Coast axed the product line and instead focused on Dungeons & Dragons 3rd Edition.
Star*Drive
The main far-future setting of the Alternity line. Star*Drive is set at the dawn of the 26th century, and humanity has spread out across the Orion Arm. The first galactic war saw the end of colonial rule from Earth, while the century-long second galactic war forged the colonies into a dozen powerful stellar nations united into three alliances. The growing nations have encountered dozens of sentient species, of which several stand out.
- Fraal: The gray aliens; slender, telepathic humanoids with black eyes, the fraal arrived in the Sol system thousands of years ago, having forgotten both their homeworld and their destination. Over the centuries they attempted to communicate with humanity but without success until humans began to colonize the solar system. The combination of terran mass reactor technology and fraal gravitic propulsion made the stardrive possible, allowing faster than light travel.
- Aleerians (Mechalus): Nice borg; a fully cyborgized species. Typically pacifists but they don't regard cyberwar to be violent. Their trade agreement with the Rigunmor Consortium leases mechalus recruits as contract hackers and tech experts for anyone who can pay.
