Question: Which is a real-estate based board game, Skirrid or Solarquest?

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: Ploy (board game): Ploy is an abstract strategy board game for two or four players, played on a 9x9 board with a set of 15 pieces (2-handed) or 9 pieces (4-handed and partnership games) per player. Pieces have various horizontal, vertical or diagonal moves somewhat like chess pieces, except directions of movement are limited; pieces change directions of movement by "rotating". Object of the game is to capture the opponent's "Commander" (analogous to the king in chess), or all of his other pieces.
Document 3: Kerbal Space Program: Kerbal Space Program (KSP) is a space flight simulation video game developed and published by Squad for Microsoft Windows, OS X, Linux, PlayStation 4, Xbox One, with a Wii U version that was supposed to be released at a later date. The developers have stated that the gaming landscape has changed since that announcement and more details will be released soon. In the game, players direct a nascent space program, staffed and crewed by humanoid aliens known as "Kerbals". The game features a realistic orbital physics engine, allowing for various real-life orbital maneuvers such as Hohmann transfer orbits and bi-elliptic transfer orbits.
Document 4: Sixteen Soldiers: Sixteen Soldiers is a two-player abstract strategy board game from Sri Lanka. It also comes from India under the name Cows and Leopards. A variant of this game is also popular in Bangladesh, where it is known as Sholo guti (Sixteen pieces). The game is similar to draughts and Alquerque as players hop over one another's pieces to capture them. However, unlike draughts and standard Alquerque, the game is played on an expanded Alquerque board consisting of four triangular boards attached to the four sides of an Alquerque board. Also, pieces can move and capture in any direction from the beginning. There is no promotion to King. Its actual closest relatives are Peralikatuma and Kotu Ellima which are also from the Indian subcontinent. The only real difference between these three closely related games is the number of pieces. In Sixteen Soldiers, each player has 16 pieces hence the name of the game. In Peralikatuma, each player has 23 pieces. In Kotu Ellima, each player has 24 pieces. Sixteen Soldiers is also related to the Indonesian game of Permainan-Tabal.
Document 5: 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.

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 8: Scrabble: Scrabble is a word game in which two to four players score points by placing tiles bearing a single letter onto a board divided into a 15×15 grid of squares.

Document 9: 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. The game was first marketed as a board game in Denmark under the name Con-tac-tix, and Parker Brothers marketed a version of it in 1952 called Hex; they are no longer in production. Hex can also be played with paper and pencil on hexagonally ruled graph paper.
Document 10: Rummikub: Rummikub is a tile-based game for two to four players, combining elements of the card game rummy and mahjong. There are 104 number tiles in the game (valued 1 to 13 in four different colors, two copies of each) and two jokers. Players have 14 or 16 tiles initially and take turns putting down tiles from their racks into sets (groups or runs) of at least three, drawing a tile if they cannot play. In the Sabra version (the most common and popular), the first player to use all their tiles scores a positive score based on the total of the other players' hands, while the losers get negative scores. An important feature of the game is that players can work with the tiles that have already been played.
Document 11: 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 12: 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.

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.
