Rhythm game in the context of Video game genres

Video game music (VGM) is the soundtrack that accompanies video games. Early video game music was once limited to sounds of early sound chips, such as programmable sound generators (PSG) or FM synthesis chips. These limitations have led to the style of music known as chiptune, which became the sound of the early video games.

With technological advances, video game music has grown to include a wider range of sounds. Players can hear music in video games over a game's title screen, menus, and gameplay. Game soundtracks can also change depending on a player's actions or situation, such as indicating missed actions in rhythm games, informing the player they are in a dangerous situation, or rewarding them for specific achievements.

Donkey Kong is a video game series and media franchise created by the Japanese game designer Shigeru Miyamoto for Nintendo. It follows the adventures of Donkey Kong, a large, powerful gorilla, and other members of the Kong family of apes. Donkey Kong games include the original arcade game trilogy by Nintendo R&D1; the Donkey Kong Country series by Rare and Retro Studios; and the Mario vs. Donkey Kong series by Nintendo Software Technology. Various studios have developed spin-offs in genres such as edutainment, puzzle, racing, and rhythm. The franchise also incorporates animation, printed media, theme parks, and merchandise.

Miyamoto designed the original 1981 Donkey Kong to repurpose unsold arcade cabinets following the failure of Radar Scope (1980). It was a major success and was followed by the sequels Donkey Kong Jr. (1982) and Donkey Kong 3 (1983). Nintendo placed the franchise on a hiatus as it shifted focus to the spin-off Mario franchise. Rare's 1994 reboot, the Super Nintendo Entertainment System (SNES) game Donkey Kong Country, reestablished Donkey Kong as a major Nintendo franchise. Rare developed Donkey Kong games for the SNES, Game Boy, and Nintendo 64 until it was acquired by Microsoft in 2002; subsequent games were developed by Nintendo, Retro Studios, Namco and Paon. After Donkey Kong Country: Tropical Freeze (2014), the franchise went on another hiatus, which ended with Donkey Kong Bananza (2025).

Space Invaders is a fixed shooter video game released in 1978 by Taito. It was designed by Tomohiro Nishikado, who was inspired by other media such as Breakout, The War of the Worlds and Star Wars. It is one of the forerunners of modern video gaming and helped expand the video game industry from a novelty to a global industry. It was first released as an arcade game and later remade on different platforms; re-releases include ported and updated versions. Ported versions generally feature different graphics and additional gameplay options, including moving defense bunkers, zigzag shots, invisible aliens, and two-player modes. Space Invaders is one of the highest-grossing video game franchises of all time.

Taito released numerous sequels and spin-offs, many of which have also been remade on multiple platforms, including home consoles and handheld devices. Follow up titles are typically released in celebration of the original's anniversary. The first sequels were primarily released in arcades, while later titles were released on portable devices. Sequels often added power-ups and incorporated new gameplay mechanics—like three-dimensional playing fields, bosses, and rhythm-action—to the original's design. Most titles were released internationally, though some are exclusive to select regions. The games have received different receptions: the Atari 2600 port of the original became the video game industry's first "killer app", while some sequels were regarded as insignificant updates. Space Invaders and several of its arcade sequels are often included in video game compilations released by Taito.

Guitar Hero is a series of rhythm games first released in 2005, in which players use a guitar-shaped game controller to simulate playing primarily lead, bass, and rhythm guitar across numerous songs. Players match notes that scroll on-screen to colored fret buttons on the controller, strumming the controller in time to the music in order to score points, and keep the virtual audience excited. The games attempt to mimic many features of playing a real guitar, including the use of fast-fingering hammer-ons and pull-offs and the use of the whammy bar to alter the pitch of notes. Most games support single player modes, typically a Career mode to play through all the songs in the game, as well as competitive and cooperative multiplayer modes. With the introduction of Guitar Hero World Tour in 2008, the game includes support for a four-player band including vocals and drums. The series initially used mostly cover versions of songs created by WaveGroup Sound, but most recent titles feature soundtracks that are fully master recordings, and in some cases, special re-recordings, of the songs. Later titles in the series feature support for downloadable content in the form of new songs.

In 2005, RedOctane, a company specializing in the manufacture of unique game controllers, was inspired to create Guitar Hero based on its experience creating hardware for Konami's GuitarFreaks arcade game. It enlisted Harmonix, which had previously developed several music video games, for development assistance. The first game in the series was made on a budget of US$1 million. The series became extremely successful, leading to the acquisition of RedOctane by Activision in 2007. Harmonix was acquired by MTV Games and went on to create the Rock Band series of music games in the same vein as Guitar Hero. Activision brought Neversoft (primarily known for their Tony Hawk series of skateboarding games) on board for future development duties. Additional companies, such as Budcat Creations and Vicarious Visions, have assisted in the adaptation of the games for other systems.

An action game is a video game genre that emphasizes physical challenges, including hand–eye coordination and reaction time. The genre includes a large variety of sub-genres, such as fighting games, beat 'em ups, shooter games, rhythm games and platform games. Multiplayer online battle arena and some real-time strategy games are also considered action games.

In an action game, the player typically controls a character often in the form of a protagonist or avatar. This player character must navigate a level, collecting objects, avoiding obstacles, and battling enemies with their natural skills as well as weapons and other tools at their disposal. At the end of a level or group of levels, the player must often defeat a boss enemy that is more challenging and often a major antagonist in the game's story. Enemy attacks and obstacles deplete the player character's health and lives, and the player receives a game over when they run out of lives.

Bemani, stylized in all caps, is Konami's music video game division. Originally named the Games & Music Division (G.M.D.), it changed its name in honor of its first and most successful game, Beatmania, and expanded into other music-based games, most notably rhythm games such as Dance Dance Revolution, GuitarFreaks, and DrumMania.
