Retro video games refer to classic video games that were popular from the late 1970s to the early 1990s. These games often feature simple graphics and gameplay mechanics, relying on 2D pixel art and straightforward controls. Iconic titles include Pac-Man, Super Mario Bros., and Tetris, which have left a lasting impact on the gaming industry. Many retro games were played on early gaming consoles like the Atari 2600 and the Nintendo Entertainment System (NES). Today, they are celebrated for their nostalgia and influence, often being re-released on modern platforms or included in collections for new generations to enjoy.
