It was created by Decipher, Inc., which also produced the "Star Trek Customizable Card Game" and "The Lord of the Rings Trading Card Game".

Operation and oversight of the game was then taken over by a Decipher created volunteer group called the Star Wars Customizable Card Game Players Committee. To date, the Players Committee, or PC, still runs the game and creates new cards known as "virtual cards" that are released online in PDF format, and can then be printed and played with. "SW:CCG" can also be played online: Holotable.com is the official Player Committee platform.

Context_5 : Car Wars: The Card Game is a card game version of Steve Jackson Games' Car Wars miniatures game. Players have a card in front of them to represent the car that they're using to battle other players. In turn, each player plays attack cards to try to do damage to the other players' cars, and the other players respond with armor and maneuver cards to avoid the damage. The object of the game is to make sure your car is the last one functional. Context_6 : Seven-card stud, also known as Seven-Toed Pete or Down-The-River is a variant of stud poker. Until the recent increase in popularity of Texas hold 'em, seven-card stud was the most widely played poker variant in home games across the United States, and in casinos in the eastern part of the country. Two to eight players is common, though eight may require special rules for the last cards dealt if no players fold. With experienced players who fold often, even playing with nine players is possible. Context_7 : Happy Families is a traditional card game, usually with a specially made set of picture cards, featuring illustrations of fictional families of four, most often based on occupation types. The object of the game is to collect complete families. The player whose turn it is asks another player for a specific card from the same family as a card that the player already has. If the asked player has the card, he gives it to the requester and the requester can then ask any player for another card. If the asked player does not have the card, it becomes his turn and he asks another player for a specific card. Play continues in this way until no families are separated among different players. The player with the most cards wins. One of the rules states that a player cannot ask for a certain card to deceive any player if he does not have a card in the set he is asking for. The game can be adapted for use with an ordinary set of playing cards (see Go Fish). Context_8 : Richard Channing Garfield (born June 26, 1963) is an American game designer. Garfield created "", which is considered to be the first modern collectible card game (CCG). "Magic" debuted in 1993, and its success spawned many imitations. Garfield oversaw the successful growth of "Magic" and followed it with other game designs. Garfield also designed the living card game (LCG) "Netrunner", as well as "BattleTech", "" (originally known as "Jyhad"), "Star Wars Trading Card Game", the card game "The Great Dalmuti", and the board game "RoboRally". He also created a variation of the card game Hearts called Complex Hearts. Garfield first became passionate about games when he played the roleplaying game "Dungeons & Dragons", so he designed "Magic" decks to be customizable like roleplaying characters. Garfield and "Magic "are in the Adventure Gaming Hall of Fame. Context_9 : Gundam War: Mobile Suit Gundam the Card Game also known simply as Gundam War is a collectible card game based on the Gundam anime series produced by Bandai. Players can simulate battles in the anime series. The game is designed for 2 players, though there may be different fan-created multiplayer rules. This game is sometimes confused with the Gundam M.S. War Trading Card Game, since both are published by Bandai and are based on the Gundam series. Context_10 : Briscola (] ; Sicilian: "briscula" , Neapolitan: "briscula" or "brisca", Spanish and Catalan: "brisca" , Portuguese: "bisca" , Montenegrin and Croatian: "briskula" , Slovene: "briskola" , Maltese: "bixkla" , Libyan: "skembeel "), one of Italy's most popular games together with Scopa and Tressette, and a little-changed descendant of Brusquembille, the ancestor of Briscan and Bezique, is a Mediterranean trick-taking card game for two to six players played with a standard Italian 40-card deck. Apart from the Northern Mediterranean, the game is also popular in Puerto Rico. It is usually considered to be an elaboration from an original Dutch card game related to klaviaas, perhaps transmitted by sailors. (A confirming piece of evidence comes from the curious expression when one team wins all the points, called a cappotto. This is a puzzling term, as it means coat jacket in Italian, but may descend from Kapot, meaning complete defeat in Dutch). Relative to the Dutch game, where players need to follow suit, briscola rules allow any card to be played. This makes the game more unpredictable, as trump cards cannot be easily neutralized and may be played strategically at any point in time. fact_1 : Michael Keiner (born February 8, 1959 in Wetzlar, Germany) is a German poker player best known for winning a Seven-card stud WSOP bracelet in 2007. fact_2 : Two to eight players is common, though eight may require special rules for the last cards dealt if no players fold.
