EXPLANATION

The first commercially available video game, Pong (Atari 1973), was introduced 11 years after Spacewar!
Pong is a simple concept that has turned out to be surprisingly durable even though the graphics are simply white rectangles on a black background. In the beginning, Pong was placed at entertainment venues, markets, and fun fairs, next to mechanical pastimes and as a supplement to these. This is the same kind of place where the game Space Invaders (Taito 1977) was also introduced. Space Invaders defines most of the basic parameters of what I call the classical action game: A player controls an object/an actor against some enemies; a score is kept; the game is real-time and requires fast reflexes; the player has a fixed amount of lives (typically three); the game is based on successive levels of increasing difficulty; the game (or just the title) places the player’s action as part of a minimal narrative.
