Question: What was first published, Solarquest or CirKis?

full_context: Document 1: Solarquest: SolarQuest is a space-age real estate trading board game published in 1985 and developed by Valen Brost, after his having conceived the idea in 1976. The game is patterned after "Monopoly" but replaces pewter tokens with rocketships and hotels with metallic fuel stations. Players travel around the sun acquiring planet, moon, and man-made space structure monopolies while fending off attacks. They seek to knock their opponents out of the game through bankruptcy, as well as optional laser blasts and dwindling fuel supplies (when using the Advanced Play ruleset).
Document 2: Buck Rogers – Battle for the 25th Century: Buck Rogers – Battle for the 25th Century is a strategy board game published in 1988 by TSR, Inc.. The game uses the setting and themes of the 1930s Buck Rogers serials, and the design of 1950s space-race-era propaganda. The units and game-play for the game work similarly to "Axis & Allies", with naval units being replaced by space ships and two different kinds of infantry instead of one. The game was produced in large quantities, but never sold well and didn't last past a second edition.
Document 3: Masterpiece (game): Masterpiece is a board game by Parker Brothers, now a brand of Hasbro. Players participate in auctions for famous works of art. It was invented by Joseph M. Burck of Marvin Glass and Associates and originally published in 1970 by Parker Brothers, and then published again in 1976 and 1996. The game is now out-of-print. In this game, players compete with other players to bid on potentially valuable paintings, and negotiate with other players to trade these works of art, build a portfolio, amass money, and win the game. The top value of a painting in the 1970 edition is $1 million, and $10 million in the 1996 edition; however, getting the full value for the painting requires some luck in landing on the right square on the board to sell a painting to the bank.

Document 7: Pente: Pente is a strategy board game for two or more players, created in 1977 by Gary Gabrel, a dishwasher at Hideaway Pizza, in Stillwater, Oklahoma. Customers played Pente at Hideaway Pizza on checkerboard tablecloths while waiting for their orders to arrive. Thirty years later, patrons are still playing Pente at Hideaway Pizza, although now with roll-up Pente boards. Pente is based on the Japanese game ninuki-renju, a variant of renju or gomoku that is played on a Go board of 19x19 intersections with white and black stones. Like "ninuki-renju," Pente allow captures, but Pente added a new opening rule. In the nineteenth century, "gomoku" was introduced to Britain where it was known as "Go Bang."

Document 10: Acquire: Acquire is a multi-player mergers and acquisitions themed board game. It is played with tiles representing hotels that are arranged on the board, play money and stock certificates. The object of the game is to earn the most money by developing and merging hotel chains. When a chain in which a player owns stock is acquired by a larger chain, players earn money based on the size of the acquired chain. At the end of the game, all players liquidate their stock in order to determine which player has the most money. It was one of the most popular games in the 1960s 3M bookshelf game series, and the only one still published in the United States.
Document 11: Squatter (game): Squatter is a board game that was launched at the Royal Melbourne Show in 1962, invented by Robert Crofton Lloyd. With more than 500,000 games sold in Australia alone, it became the most successful board game ever developed in Australia. Superficially, Squatter has the appearance of a "Monopoly"-type game. However, unlike Monopoly, all players remain in the game until the end. Players each start the game with their own sheep station and aim to be the first player to improve and irrigate their pastures and then fully stock their sheep station. Players run their sheep station as a business venture, to earn enough money to pay for the seasonal running expenses and to finance the improvements that are required to win the game. The Squatter game presents players with a mixture of strategy and luck that reflects the many challenges facing any form of livestock raising. These challenges include droughts, floods and bushfires, as well as disease, variable livestock prices, and luck. In 1999, a version became available on PC CD-ROM. However the PC version was not commercially successful and is no longer available.

Document 14: Hex (board game): Hex is a strategy board game for two players played on a hexagonal grid, theoretically of any size and several possible shapes, but traditionally as an 11×11 rhombus. Players alternate placing markers or stones (Go stones make ideal playing pieces) on unoccupied spaces in an attempt to link their opposite sides of the board in an unbroken chain. One player must win; there are no draws. The game has deep strategy, sharp tactics and a profound mathematical underpinning related to the Brouwer fixed-point theorem. It was invented in the 1940s independently by two mathematicians, Piet Hein and John Nash.
