Alien Legacy is a sci-fi strategy game developed by Ybarra Productions and published by Sierra On-Line in 1994 for MS-DOS.

The game includes elements of city construction, research, resource management, industrial production and combat.

Players must colonize a star system light-years from Earth by building planetary cities and Space Stations.

The Calypso, Tantalus, and similar ships were sent to colonize other star systems due to the threat of humanity's extinction on Earth as a result of an interstellar war.

He found the plot to be quite linear, and while events may happen differently on replay, felt no need to return to the game after completing it.
