Triplanetary (board Game)
''Triplanetary'' is a science fiction board wargame originally published by Game Designers' Workshop in 1973. The game is a simulation of space ship travel and combat within the Solar System in the early 21st Century. History First edition ''Triplanetary'' was designed by Marc W. Miller and John Harshman, loosely based on novels and short stories from the Golden Age of Science Fiction, particularly the '' Future History'' works of Robert Heinlein. ''Triplanetary'' was originally conceived as the first part of a proposed series of games that was to be named ''"The Stars! The Stars!"'' As Miller related, a late-night session of '' Lensman'' with Harshman using blank hex-grid battle board combat "inspired the design for ''Triplanetary'', with its image of our solar system and use of vector movement". In 1976, GDW released ''Triplanetary Variant V/2'', an expansion of the suggested "Prospecting" scenario that was part of the original Errata sheets. Second edition GDW publish ...

Game Designers' Workshop
Game Designers' Workshop (GDW) was a wargame and role-playing game publisher from 1973 to 1996. Many of their games are now carried by other publishers. History Game Designers' Workshop was originally established June 22, 1973. The founding members consisted of Frank Chadwick, Rich Banner, Marc Miller, and Loren Wiseman. GDW acquired the Conflict Games Company from John Hill in the early 1970s. GDW published a new product approximately every twenty-two days for over twenty years. In an effort to bridge the gap between role players, board wargamers and miniature wargamers, the company published RPGs with fantastic settings alongside games with realistic themes including rulesets for 15mm and 20mm miniatures set during the American Civil War, World War I, World War II, and the modern era; and boardgames involving these eras such as the ''Air Superiority'' series and ''Harpoon''. The company disbanded February 29, 1996 after suffering financial troubles. Products Role-pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TSR (company)
TSR, Inc. was an American game publishing company, best known as the original publisher of ''Dungeons & Dragons'' (''D&D''). Its earliest incarnation, Tactical Studies Rules, was founded in October 1973 by Gary Gygax and Don Kaye. Gygax had been unable to find a publisher for ''D&D'', a new type of game he and Dave Arneson were co-developing, so founded the new company with Kaye to self-publish their products. Needing financing to bring their new game to market, Gygax and Kaye brought in Brian Blume in December as an equal partner. ''Dungeons & Dragons'' is generally considered the first tabletop role-playing game (TTRPG), and established the genre. When Kaye died suddenly in 1975, the Tactical Studies Rules partnership restructured into TSR Hobbies, Inc. and accepted investment from Blume's father Melvin. With the popular ''D&D'' as its main product, TSR Hobbies became a major force in the games industry by the late 1970s. Melvin Blume eventually transferred his shares to his ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth the mass of the Sun. Jupiter is the List of brightest natural objects in the sky, third brightest natural object in the Earth's night sky after the Moon and Venus, and it has been observed since Pre-history, prehistoric times. It was named after the Jupiter (mythology), Roman god Jupiter, the king of the gods. Jupiter is primarily composed of hydrogen, but helium constitutes one-quarter of its mass and one-tenth of its volume. It probably has a rocky core of heavier elements, but, like the other giant planets in the Solar System, it lacks a well-defined solid surface. The ongoing contraction of Jupiter's interior generates more heat than it receives from the Sun. Because of its rapid rotation, the planet' ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Asteroid Belt
The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. About 60% of its mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is calculated to be 3% that of the Moon. Ceres, the only object in the asteroid belt large enough to be a dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters less than 600 km. The remaining bodies range down to the size of a dust particle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...

Venus
Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth at dark conditions and being visible to the naked eye in broad daylight. Venus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a very weak induced magnetosphere. The atmosphere of Venus, mainly consists of carbon dioxide, and is the densest and hottest of the four terrestrial planets at the surface. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of , the carbon dioxide gas at Venus's surface is in the ...

Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter (board Wargames)
A counter is usually a small cardboard square moved around on the map of a board wargame to represent relevant information or determine certain things. The first wargame based on cardboard counters was ''War Tactics or Can Great Britain Be Invaded?'' invented by Arthur Renals of Leicester in 1911.Christopher Lewin, ''War Games and their History'', Chapter 8, Fonthill Media, Stroud (GB) 2012, The first wargame bringing counters to a mass-market was Tactics (game), ''Tactics'', invented by Charles S. Roberts in 1952. Traditional wargames typically have hundreds of counters (''The Russian Campaign'', 225; ''Squad Leader#GI: Anvil of Victory, GI: Anvil of Victory'', 856; ''Terrible Swift Sword (game), Terrible Swift Sword'', 2,000). ''Squad Leader'' had counters of different sizes: 520 -inch counters and 192 -inch, with the different sizes used for different purposes. Boardgame counters are often closely related to military map marking symbols, such as those seen in the NATO standar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetate
An acetate is a salt (chemistry), salt formed by the combination of acetic acid with a base (e.g. Alkali metal, alkaline, Alkaline earth metal, earthy, Transition metal, metallic, nonmetallic or radical Radical (chemistry), base). "Acetate" also describes the conjugate acid, conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula . The neutral molecules formed by the combination of the acetate ion and a ''positive'' ion (called a cation) are also commonly called "acetates" (hence, ''acetate of lead'', ''acetate of aluminum'', etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic ion, polyatomic anion , or . Most of the approximately 5 billion kilograms of acetic acid produced annually in industry are used in the production of acetates, which usually take the form of polymers. In nature, acetate is the most common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hex Map
A hex map, hex board, or hex grid is a game board design commonly used in wargames of all scales. The map is subdivided into a hexagonal tiling, small regular hexagons of identical size. Advantages and disadvantages The primary advantage of a hex map over a traditional square grid map is that the distance between the center of each and every pair of adjacent hex cells (or ''hex'') is the same. By comparison, in a square grid map, the distance from the center of each square cell to the center of the four diagonal adjacent cells it shares a corner with is times that of the distance to the center of the four adjacent cells it shares an edge with. This equidistant property of all adjacent hexes is desirable for games in which the measurement of movement is a factor. The other advantage is the fact that neighbouring cells always share edges; there are no two cells with contact at only a point. One disadvantage of a hex map is that hexes have adjacent cells in only six directions ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
