Nintendo Entertainment System in the context of "Mario"

A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time, either locally on the same computing system (couch co-op), on different computing systems via a local area network, or via a wide area network, most commonly the Internet (e.g. World of Warcraft, Call of Duty, DayZ). Multiplayer games usually require players to share a single game system or use networking technology to play together over a greater distance; players may compete against one or more human contestants, work cooperatively with a human partner to achieve a common goal, or supervise other players' activity. Due to multiplayer games allowing players to interact with other individuals, they provide an element of social communication absent from single-player games.

The history of multiplayer video games extends over several decades, tracing back to the emergence of electronic gaming in the mid-20th century. One of the earliest instances of multiplayer interaction was witnessed with the development of Spacewar! in 1962 for the DEC PDP-1 computer by Steve Russell and colleagues at the MIT. During the late 1970s and early 1980s, multiplayer gaming gained momentum within the arcade scene with classics like Pong and Tank. The transition to home gaming consoles in the 1980s further popularized multiplayer gaming. Titles like Super Mario Bros. for the NES and Golden Axe for the Sega Genesis introduced cooperative and competitive gameplay. Additionally, LAN gaming emerged in the late 1980s, enabling players to connect multiple computers for multiplayer gameplay, popularized by titles like Doom and Warcraft: Orcs & Humans. Players can also play together in the same room using splitscreen.

Super Mario Bros. is a 1985 platform game developed and published by Nintendo for the Nintendo Entertainment System (NES). Directed and produced by Shigeru Miyamoto, it is the successor to the 1983 arcade game Mario Bros. and the first game in the Super Mario series. Players control Mario, or his brother Luigi in the multiplayer mode, to traverse the Mushroom Kingdom to rescue Princess Toadstool from King Koopa (later named Bowser). They traverse side-scrolling stages while avoiding hazards such as enemies and pits and collecting power-ups such as the Super Mushroom, Fire Flower and Starman.

Miyamoto and Takashi Tezuka designed Super Mario Bros. as a culmination of the team's experience working on Devil World and the side-scrollers Excitebike and Kung Fu. Miyamoto wanted to create a more colorful platform game with a scrolling screen and larger characters. The team designed the first level, World 1-1, as a tutorial for platform gameplay. Koji Kondo's soundtrack is one of the earliest in video games, making music a centerpiece of the design.

Nintendo Co., Ltd. is a Japanese multinational video game company headquartered in Kyoto. It develops, publishes, and releases both video games and video game consoles.

The history of Nintendo began when craftsman Fusajiro Yamauchi founded the company to produce handmade hanafuda playing cards. After venturing into various lines of business and becoming a public company, Nintendo began producing toys in the 1960s, and later video games. Nintendo developed its first arcade games in the 1970s, and distributed its first system, the Color TV-Game in 1977. The company became internationally dominant in the 1980s after the arcade release of Donkey Kong (1981) and the Nintendo Entertainment System, which launched outside of Japan alongside Super Mario Bros. in 1985.

The Super Nintendo Entertainment System, commonly shortened to Super Nintendo, Super NES or SNES, is a 16-bit home video game console developed by Nintendo that was released in 1990 in Japan, 1991 in North America, 1992 in Europe and Oceania and 1993 in South America. In Japan, it is called the Super Famicom (SFC). In South Korea, it is called the Super Comboy and was distributed by Hyundai Electronics. The system was released in Brazil on August 30, 1993, by Playtronic. In Russia and CIS, the system was distributed by Steepler from 1994 until 1996. Although each version is essentially the same, several forms of regional lockout prevent cartridges for one version from being used in other versions.

The Super NES is Nintendo's second programmable home console, following the Nintendo Entertainment System (NES). The console introduced advanced graphics and sound capabilities compared with other systems at the time. It was designed to accommodate the ongoing development of a variety of enhancement chips integrated into game cartridges to be more competitive into the next generation.

The history of video games began in the 1950s and 1960s as computer scientists began designing simple games and simulations on minicomputers and mainframes. Spacewar! was developed by Massachusetts Institute of Technology (MIT) student hobbyists in 1962 as one of the first such games on a video display. The first consumer video game hardware was released in the early 1970s. The first home video game console was the Magnavox Odyssey, and the first arcade video games were Computer Space and Pong. After its home console conversions, numerous companies sprang up to capture Pong's success in both the arcade and the home by cloning the game, causing a series of boom and bust cycles due to oversaturation and lack of innovation.

By the mid-1970s, low-cost programmable microprocessors replaced the discrete transistor–transistor logic circuitry of early hardware, and the first ROM cartridge-based home consoles arrived, including the Atari Video Computer System (VCS). Coupled with rapid growth in the golden age of arcade video games, including Space Invaders and Pac-Man, the home console market also flourished. The 1983 video game crash in the United States was characterized by a flood of too many games, often of poor or cloned qualities, and the sector saw competition from inexpensive personal computers and new types of games being developed for them. The crash prompted Japan's video game industry to take leadership of the market, which had only suffered minor impacts from the crash. Nintendo released its Nintendo Entertainment System in the United States in 1985, helping to rebound the failing video games sector. The latter part of the 1980s and early 1990s included video games driven by improvements and standardization in personal computers and the console war competition between Nintendo and Sega as they fought for market share in the United States. The first major handheld video game consoles appeared in the 1990s, led by Nintendo's Game Boy platform.

A video game clone is either a video game or a video game console very similar to, or heavily inspired by, a previous popular game or console. Clones are typically made to take financial advantage of the popularity of the cloned game or system, but clones may also result from earnest attempts to create homages or expand on game mechanics from the original game. An additional motivation unique to the medium of games as software with limited compatibility, is the desire to port a simulacrum of a game to platforms that the original is unavailable for or unsatisfactorily implemented on.

The legality of video game clones is governed by copyright and patent law. In the 1970s, Magnavox controlled several patents to the hardware for Pong, and pursued action against unlicensed Pong clones that led to court rulings in their favor, as well as legal settlements for compensation. As game production shifted to software on discs and cartridges, Atari sued Philips under copyright law, allowing them to shut down several clones of Pac-Man. By the end of the 1980s, courts had ruled in favor of a few alleged clones, and the high costs of a lawsuit meant that most disputes with alleged clones were ignored or settled through to the mid-2000s. In 2012, courts ruled against alleged clones in both Tetris Holding, LLC v. Xio Interactive, Inc. and Spry Fox, LLC v. Lolapps, Inc., due to explicit similarities between the games' expressive elements.
