Alternity
The last RPG from TSR
In 1998 before T.S.R went bankrupt 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,Will and Personality and take on roles such as Combat Spec, Tech Op and DIplomat. Using a dual dice mechanic of rolling a control die , a d20, and other dice such as d4's but dice size could change due to circumstantial modifiers to as much as a roll of 3d20. The aim being to roll low to get a success under a target number such as a skill and 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 several backgrounds sold for it which even included a pen and paper version of the Starcraft PC game by Blizzard. The product line was discontinued but settings such as Dark Matter survived onto D20 Modern.
