Lunar Pool (known as Lunar Ball (ルナーボール, Runā Bōru?) in Japan) is a rough simulation of pool (pocket billiards) combined with aspects of miniature golf, created by Compile for the Nintendo Entertainment System and MSX, in which each stage is a differently shaped pool table. The object is to knock each ball into a pocket using a cue ball. There are sixty levels to choose from, and the friction of the table is adjustable. The Japanese Lunar Ball version often appears on Famicom clone systems and pirated multi-game cartridges, such as the Power Player Super Joy III. It was released for the Wii on the North American Virtual Console on October 22, 2007.

M.U.S.C.L.E., (Millions of Unusual Small Creatures Lurking Everywhere), was a toyline of 2-inch tall monochromatic PVC gum wrestling figures produced in the United States from 1985 to 1988. The story involved intergalactic wrestlers fighting for supremacy of the universe. The toy line itself was straight forward and collectors continue to make the line a viable hobby. The US line included 236 official figures, a boardgame, a NES game entitled M.U.S.C.L.E., a championship belt figure holder, and a wrestling ring playset. The figures were distributed in clear, blister-packed random 4-packs, semiopaque garbage can 10-packs, and boxed fixed sculpt 28 packs. For a short time, the figures were also distributed as a bonus in Nestlé Quik (now known as Nesquik) cans.

Major League Baseball (MLB) is a professional baseball organization that constitutes one of the four major professional sports leagues in North America. MLB teams play in the American League (AL) and National League (NL), which operated as separate legal entities from 1901 and 1876 respectively. In 2000, the leagues merged into a single organization led by the Commissioner of Baseball. The organization oversees minor league baseball leagues, which operate about 240 teams affiliated with the major-league clubs. With the International Baseball Federation, the league also manages the international World Baseball Classic tournament. Baseball's first professional team was founded in Cincinnati in 1869. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one team or league to another. The period before 1920 in baseball was known as the dead-ball era; players rarely hit home runs during this time. Baseball survived a game-throwing incident known as the Black Sox Scandal in the 1919 World Series. Baseball rose in popularity in the 1920s, and survived potential downturns during the Great Depression and World War II. Shortly after the war, baseball's color barrier was broken by Jackie Robinson. The 1950s and 1960s were a time of expansion for the AL and NL, then new stadiums and artificial turf surfaces began to change the game in the 1970s and 1980s. Home runs dominated the game during the 1990s, and media reports began to discuss the use of anabolic steroids among MLB players in the mid-2000s. In 2006, an investigation produced the Mitchell Report, which implicated many MLB players in the use of performance-enhancing substances, including at least one player from each MLB team. Today, MLB is composed of thirty teams: twenty-nine in the United States and one in Canada. Teams in MLB play 162 games each season. Five teams in each league advance to a four-round postseason tournament that culminates in the World Series, a best-of-seven championship series between the two league champions that dates to 1903. Baseball broadcasts are aired throughout North America and in several other countries throughout the world. Games are aired on television, radio, and the internet. MLB has the highest season attendance of any sports league in the world with more than 74 million spectators in 2013.

Marble Madness is an arcade video game designed by Mark Cerny, and published by Atari Games in 1984. It is a platform game in which the player must guide an onscreen marble through six courses, populated with obstacles and enemies, within a time limit. The player controls the marble by using a trackball. Marble Madness is known for using innovative game technologies. It was Atari's first to use the Atari System 1 hardware and to be programmed in the C programming language. The game was also one of the first to use true stereo sound; previous games used either monaural sound or simulated stereo. In designing the game, Cerny drew inspiration from miniature golf, racing games, and artwork by M. C. Escher. He aimed to create a game that offered a distinct experience with a unique control system. Cerny applied a minimalist approach in designing the appearance of the game's courses and enemies. Throughout development, he was frequently impeded by limitations in technology and had to forgo several design ideas. Upon its release, Marble Madness was commercially successful, becoming a profitable arcade game. Praise among critics focused on the game's difficulty, unique visual design, and stereo soundtrack. The game was ported to numerous platforms and inspired the development of other games. A sequel was developed and planned for release in 1991, but canceled when location testing showed the game could not succeed in competition with other titles.
