- Platformer — Space Panic, a 1980 arcade release, is sometimes credited as the first platform game.[468] It was clearly an influence on the genre, with gameplay centered on climbing ladders between different floors, a common element in many early platform games. Donkey Kong, an arcade game created by Nintendo, released in July 1981, was the first game that allowed players to jump over obstacles and across gaps, making it the first true platformer.[469]
- Metroidvania — Spawned by the Metroid and Castlevania, with template based on Metroid (1986), Castlevania II (1987), Super Metroid (1994) and Castlevania: Symphony of the Night (1997),[470] but predated by Brain Breaker (1985).[471][472][473]
- Scrolling platformer — The first platform game to use scrolling graphics was Jump Bug (1981), a simple platform-shooter developed by Alpha Denshi.[474] In August 1982, Taito released Jungle King,[475] which featured scrolling jump and run sequences that had players hopping over obstacles. Namco took the scrolling platformer a step further with the 1984 release Pac-Land. Pac-Land came after the genre had a few years to develop, and was an evolution of earlier platform games, aspiring to be more than a simple game of hurdle jumping, like some of its predecessors.[476] It closely resembled later scrolling platformers like Wonder Boy and Super Mario Bros. and was probably a direct influence on them. It also had multi-layered parallax scrolling.[477][478]
- Point-and-click — Legends of Star Arthur: Planet Mephius, released by T&E Soft in July 1983, introduced a point-and-click interface, utilizing a cursor to interact with objects.[479] A similar point-and-click cursor interface was used in Wingman (1984).[480]

- 3D rail shooter — Pre-rendered 3D graphics were first used for rail shooter Interstellar (1983).[281][282] Silpheed (1986) was a computer rail shooter with real-time 3D polygons.[492]
- Real-time strategy (RTS) — Games considered early RTS include Bokosuka Wars (1983),[493] Gain Ground (1988)[494][495] and Herzog (1988).[496] The game considered the first true RTS is Herzog Zwei (1989).[497][498][499]
- Multiplayer online battle arena (MOBA) — Herzog Zwei (1989) was a precursor to,[500][501] or early example of, the MOBA genre,[502][503] with a similar gameplay formula.[501][503][500]
- Rhythm video game — Dance Aerobics was released in 1987, and allowed players to create music by stepping on Nintendo's Power Pad peripheral. It has been called the first rhythm-action game in retrospect,[504] although the 1996 title PaRappa the Rapper has also been deemed the first rhythm game, whose basic template forms the core of subsequent games in the genre. In 1997, Konami's Beatmania sparked an emergent market for rhythm games in Japan. The company's music division, Bemani, released a number of music games over the next several years.
- Save data — The first game to save the player's high score was Taito's Space Invaders (1978).[410]

- Side-scrolling — Sega's Bomber was a side-scrolling shooter released for arcades in April 1977.[515][516] Konami's Scramble, released early 1981, introduced forced side-scrolling and was the first side‑scroller with multiple distinct levels.[447]
- Vertical scrolling — The first video game with vertical scrolling graphics was Taito's arcade game Speed Race, released in 1974.[517][518]
- Shoot 'em up — Space Invaders is frequently cited as the "first" or "original" in the genre.[447][519] Space Invaders pitted the player against multiple enemies descending from the top of the screen at a constantly increasing speed.[519] As with subsequent shoot 'em ups of the time, the game was set in space as the available technology only permitted a black background. The game also introduced the idea of giving the player a number of "lives". Space Invaders was a massive commercial success, causing a coin shortage in Japan.[520][521] The following year, Namco's Galaxian took the genre further with more complex enemy patterns and richer graphics.[447][522]
- Bullet hell — The bullet hell or danmaku genre began to emerge in the early 1990s as 2D developers needed to find a way to compete with 3D games which were becoming increasingly popular at the time. Toaplan's Batsugun (1993) is considered to be the ancestor of the modern bullet hell genre.[523] The Touhou Project series is one of the most popular bullet hell franchises.

- Psychological horror game — Silent Hill (1999) was praised for moving away survival horror games from B movie horror elements to the psychological style seen in art house or Japanese horror films,[533] due to the game's emphasis on a disturbing atmosphere rather than visceral horror.[534] The original Silent Hill is considered one of the scariest games of all time,[535] and the strong narrative from Silent Hill 2 in 2001 has made the series one of the most influential in the genre.[536] Fatal Frame from 2001 was a unique entry into the genre, as the player explores a mansion and takes photographs of ghosts in order to defeat them.[537][538]
- Texture mapping — Namco's SimDrive (SimRoad) for the Namco System 22,[394][395] with a limited 1992 release,[396] introduced 3D texture mapping.[539] It was a prototype for Ridge Racer (1993),[396] which popularized texture mapping.[540][541][542]

- Over-the-shoulder — Resident Evil 4 (2005) redefined the third-person shooter genre[553] with its "over the shoulder" offset camera angles, where the camera is placed directly over the right shoulder and therefore doesn't obscure the action.[554]
- Video game mascot — Pac-Man, who debuted in Namco's 1980 arcade game Pac-Man, is recognized as the first video game mascot.[265]
- Video game music (VGM) — Dates back to the opening chiptune in Gun Fight (1975).[555] First game with continuous music was Space Invaders (1978).[556] First video game with continuous melodic background music was Rally-X (1980).[524]
- Sampling — Namco's arcade game Rally-X (1980) was the first game to use a digital-to-analog converter (DAC) to produce sampled tones instead of a tone generator.[556]
- Visual novel (VN) — The visual novel genre is a type of interactive fiction developed in Japan in the early 1990s. As the name suggests, visual novels typically have limited interactivity, as most player interaction is restricted to clicking text and graphics.[557]

- Thiamine (Vitamin B1) — Thiamine was the first of the water-soluble vitamins to be described,[591] leading to the discovery of more such trace compounds essential for survival and to the notion of vitamin. It was not until 1884 that Kanehiro Takaki (1849–1920) attributed beriberi to insufficient nitrogen intake (protein deficiency). In 1910, Japanese scientist Umetaro Suzuki succeeded in extracting a water-soluble complex of micronutrients from rice bran and named it aberic acid.

Chindōgu
Chindōgu is the Japanese art of inventing ingenious everyday gadgets that, on the face of it, seem like an ideal solution to a particular problem. However, Chindōgu has a distinctive feature: anyone actually attempting to use one of these inventions would find that it causes so many new problems, or such significant social embarrassment, that effectively it has no utility whatsoever. Thus, Chindōgu are sometimes described as "unuseless" – that is, they cannot be regarded as 'useless' in an absolute sense, since they do actually solve a problem; however, in practical terms, they cannot positively be called "useful." The term "Chindōgu" was coined by Kenji Kawakami.

Purikura, clipped from purinto kurabu, was invented by Atlus, a Tokyo-based game software company. A female employee named Sasaki Miho had noticed the popularity of stickers among schoolgirls, a craze that also generated huge sales. In 1994, Sasaki came up with the idea of combining stickers with photos and proposed it to her Atlus employers, but her male bosses did not think it worth pursuing until 1995, when they finally gave her concept a chance.

Light guns, such as the NES Zapper or those used in the House of the Dead series, are distinctly different from positional guns used by arcade games such as SEGA's Gunblade NY. ... Light guns differ from positional guns, such as in Gunblade NY (bottom), that are essentially analog joysticks. ... Positional guns are essentially analog sticks mounted in a fixed location with respect to the screen. Light guns, in contrast, have no fixed a priori relationship with a display.

The two routes to conventional gun control are light guns and positional guns. Light guns are the most common for video game systems of any type. They work optically with screen and do not keep track of location on the screen until the gun is fired. When the gun is fired, the screen blanks for a moment, and the optics in the gun register where on the screen the gun is aimed. That information is sent to the computer, which registers the shot. ... Positional guns are mounted stationary on the arcade cabinet with the ability to aim left/right and up/down. They function much like joysticks, which maintain a known location on screen at all times and register the current location when fired.

Contrary to a popular notion, Football was not the first game to use a trak-ball controller.

It cannot be overstated how influential Hydlide was on the ARPGs which followed it, nor how popular it was on both computers and the Famicom in Japan. But it is imperative you compare Hydlide only to games released that same year, to fully appreciate the merit in its ideas.

Rally-X's longest lasting emission to the video-game ether was its debut of the bonus stage, a signature of later classics like Galaga and Joust.

Deluxe Space Invaders landed in 1979. Titled Space Invaders Part II in Japan, the game replicated the frenzy of the original but didn't bring much novelty to the arcade. Kudos, however, to Taito for one innovation: The sequel featured funny little intermission scenes between levels (a precursor to the breaks in Pac-Man), in which the last invader you shot would limp off screen.

... Introduced in 1975, the GX-1 was ... In 1973, Yamaha completed development work on a prototype codenamed the GX-707. Based on cluster voltage control, this instrument could be regarded as the predecessor of the Electone GX-1. ... As the flagship model in the Electone lineup, however, this prototype was conceived of as a theatre model for use on the concert stage. With a console weighing in excess of 300 kg and a separate board required for editing tones, it was not well suited for sale to the general public, and to this day is still considered a niche instrument.", "Why digital technology in an analog synth? ... It was thus clear that new control technology would be required in order to use a limited number of circuits in a more effective manner. ... This type of device was known as a key assigner, and it can rightly be called the predecessor of today's dynamic voice allocation (DVA) technology. Back in the early seventies, when tone generators still relied on analog technology, digital circuitry was already being put to use in these key assigners.
