Galaxy Game (Arcade PDP-11) 1971

Galaxy Game is a space combat game developed in 1971.
It is the oldest arcade machine video game. It was installed at Tresidder Union at Stanford University and only one unit was built initially, although the game later included several consoles allowing users to play against each other.
Galaxy Game is an expanded version of the 1962 Spacewar!, potentially the first video game to spread to multiple computer installations. It features two spaceships, "the needle" and "the wedge", engaged in a dogfight while maneuvering in the gravity well of a star. Both ships are controlled by human players.
