Spacewar!
"Spacewar" is one of the most important and influential games in the early history of video games. It was extremely popular in the small programming community in the 1960s and was widely ported to other computer systems at the time. It has also been recreated in more modern programming languages for PDP-1 emulators. It directly inspired many other electronic games, such as the first commercial arcade video games, "Galaxy Game" and "Computer Space" (1971), and later games such as "Asteroids" (1979). In 2007, "Spacewar" was named to a list of the ten most important video games of all time, which formed the start of the game canon at the Library of Congress.
