Fast-paced gameplay, with an emphasis on movement, fighting, hand-eye coordination, and reaction time, characterises action video games. It is a rather broad genre that is used to describe games that do not fit into more specific genres such as puzzle, platform, racing, first-person shooter, or role-playing game, though shooters and platform video games can also fall under the action genre. It is popular to see elements from other types of games integrated into action video games; as a result, many people use the term action/adventure to refer to action games with a greater emphasis on adventure elements, such as exploration and/or selection. Although first-person shooters are mostly about running and shooting, they are classified as such because of the game’s unique viewpoint. Platform video games, on the other hand, are typically action games with a strong emphasis on jumping puzzles.
Since it is such a large word, it has recently been reserved for games that place a greater emphasis on movement and fighting.
Any game in which the bulk of the obstacles are physical tests of ability falls under the action genre. Other obstacles, such as races or gathering items, are sometimes used in action games, but they are not fundamental to the genre. Tactical and exploration tasks can also be present, but these games also necessitate quick reflexes and strong hand–eye coordination. Furthermore, the player is often under time constraints. Faster-paced action games are generally more difficult. 1st
History is a fascinating topic.
The majority of early arcade games, particularly Pong clones and sometimes racing games, were sports games that attempted to emulate real sports when the video game industry began in the early 1970s, following the success of Pong.
 While some action games gained prominence in the mid-1970s, with titles such as Gun Fight in 1975 and Sea Wolf in 1976, the market was still overwhelmingly dominated by sports games, despite the flood of Pong clones that ultimately led to the video game crash of 1977.
The 1978 release of the shoot ’em up game Space Invaders marked the end of the 1977 crash and the start of the golden age of arcade games.
 As a result of the commercial success of Space Invaders, the market became dominated by action games, which have remained the most common genre in arcades and on game consoles to this day.
[nine] Asteroids Deluxe from 1979 and Pac-Man from 1980 have both become classic examples of the action genre, alongside Space Invaders.  Robotron: 2084, which debuted in arcades in 1982 and went on to become a classic in the shooter genre, is another example. 1st
Similarly to how Space Invaders developed the shooter video game genre,
When Donkey Kong was released in 1981, it did the same with the platform game subgenre.
 Paperboy, published in 1984, successfully transformed the role of delivering newspapers into an action game, illustrating the genre’s versatility.
 The year also saw the rise of martial arts-themed games, with Karate Champ  creating the one-on-one fighting game subgenre and Kung-Fu Master setting the groundwork for the side-scrolling beat ’em up subgenre.
Despite the fact that DOOM, which was published in 1994, was not the first first-person shooter, it became a worldwide classic due to its emotional tone and departure from rectangular rooms and flat floors.
1st Lock-on targeting, introduced in 1998’s The Legend of Zelda: Ocarina of Time, the cover system, introduced in 1999’s WinBack, and over-the-shoulder shooting, introduced in 2005’s Resident Evil 4, have all helped third-person shooters gain prominence in recent years. (12)
