A gamer is a person who plays interactive games, especially video games, tabletop role-playing games, and skill-based card games, and who plays for usually long periods of time. Some gamers are competitive, meaning that they compete in some games for money. There are many different gamer communities around the world.

The history of video games began in the 1950s and 1960s as computer scientists began designing simple games and simulations on mainframe computers, with MIT's Spacewar! in 1962 as one of the first such games to be played with a video display.
