This home computer game is maybe the first one. It uses alphanumeric characters as game elements. The letter E was the Starship Enterprise, while C was the opposing player's ship. The asterisks shown moving on the screen are hazards such as meteors. Stationary hazards appearing as a circle with satellites in geosynchronous orbit are planets. The plus signs are photon torpedoes fired from either of the opposing ships. This game is for 2 players. |Source: exoticsciences.com]
