It was created by Steve Jackson Games and first published in 1986 at a time when most such systems were story- or genre-specific. - Star Trek is an American science fiction entertainment franchise based on the television series created by Gene Roddenberry. The first television series, simply called "Star Trek" and now referred to as "", debuted in 1966 and aired for three seasons on the television network NBC. It followed the interstellar adventures of Captain James T. Kirk (William Shatner) and his crew aboard the starship USS "Enterprise", a space exploration vessel, built by the interstellar federal republic United Federation of Planets in the twenty-third century. The "Star Trek" canon of the franchise include "The Original Series", an animated series, four television series, its film franchise and an upcoming television series scheduled to debut in 2017. - GURPS Prime Directive is a sourcebook for GURPS , first published in 2002 . - The United Federation of Planets, abbreviated as UFP and usually referred to as "the Federation", is a fictional interstellar federal republic composed of planetary sovereignties depicted in the "Star Trek" science fiction franchise. The planetary governments agree to exist semi-autonomously under a single central authority based on the Utopian principles of universal liberty, rights, and equality, and to share their knowledge and resources in peaceful cooperation and space exploration; each member world retains its own political and social structure, with the Federation itself serving as a 'United Nations'-type advisory body. - In the fictional universe of "Star Trek", the Prime Directive is the guiding principle of the United Federation of Planets. The Prime Directive, used in five of the six "Star Trek"-based series, prohibits Starfleet personnel from interfering with the internal development of alien civilizations. This conceptual law applies particularly to civilizations which are below a certain threshold of technological, scientific and cultural development; preventing starship crews from using their superior technology to impose their own values or ideals on them. Since its introduction in the first season of the , it has served as the focus of numerous episodes of the various series. As time travel became a recurring feature in the franchise, the concept was expanded as a Temporal Prime Directive, prohibiting those under its orders from interfering in historical events. - Starfleet is a fictional organization in the "Star Trek" media franchise. Within this fictional universe, Starfleet is a service maintained by the United Federation of Planets ("the Federation") as the principal means for conducting deep-space exploration, research, defense, peacekeeping, and diplomacy. While the majority of Starfleet's members are human and it is headquartered on Earth, hundreds of other species are also represented, including the majority of the franchise's protagonists. - Time travel is the concept of movement (such as by a human) between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in philosophy and fiction, but traveling to an arbitrary point in time has a very limited support in theoretical physics, and usually only in conjunction with quantum mechanics or wormholes, also known as Einstein-Rosen bridges. In a more narrow sense, one-way time travel into the future via time dilation is a well-understood phenomenon within the frameworks of special relativity and general relativity, but advancing a large amount of time is not feasible with current technology. The concept was touched upon in various earlier works of fiction, but was popularized by H. G. Wells' 1895 novel "The Time Machine", which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction. - A role-playing game system is a set of game mechanics used in a role-playing game (RPG) to determine the outcome of a character's in-game actions. - The term sourcebook (or source book) is used to describe many different kinds of books such as collections of core articles (i.e., anthology), bibliographies, biographies, printed archival sources, directories and so on.
