Brothers, the makers of Monopoly) who were then controlling 80% of the U.S. board game market, and they chose to market a Star Wars Monopoly edition instead of SolarQuest. The Monopoly brand was thus strengthened, while SolarQuest was effectively blocked from the board game market.(Valen Brost profile) Apollo 13 edition In 1995, Universal Games released an Apollo 13 edition featuring artwork from the 1995 Universal Pictures film Apollo 13. Some differences between the 1995 edition and earlier versions include: A slightly smaller playing board that now folds into a square instead of into a rectangle. New red shift cards allowing three free laser bursts at any player on the board. Elimination of refueling on an unowned planet that has been sold back to the Federation with a fuel station on it; under the new rules, a player cannot refuel unless they purchase the property from the Federation for the deed price plus $500 for the fuel station placed by the previous owner. Six more moons to buy around Neptune. Increased purchase costs for most moons. For several planets, a reduction in rent when many moons are owned (for example, rent on Ganymede if a player has eleven moons of Jupiter is $4,630, instead of $7,400). At several Federation Stations, an increase in the amount of Federons that players collect (for example, $800 instead of $200 at Federation Station II). Red shifts occur only when the player rolls a three and a one on the dice. Spaceopoly A highly simplified spinoff was published in 1997 by Valen Brost Game Co called Spaceopoly. A bit like Monopoly, players travel round the board (representing the solar system) trying to build monopolies, whilst avoiding the perils of space travel. It has secret mission cards, similar to Risk, specifying an assignment that the player can complete to win the game. The rules contain quirky provisions; for example, the last sentence of the rule on laser battles reads: "If an opponent fires a laser at your ship and rolls 12 (i.e., double sixes), your ship is totally disabled and you are out of the game. Your attacker wins all of your money and property. Exception: If you hold the 'Invented a new force field' mission card you survive the attack and automatically win the game!" Computerized versions No computerized versions have been authorized for development by Valen Brost. Reception In the August 1997 edition of Dragon
