Homeworld is a
computer game released in
1999 developed by
Relic Entertainment[?] and published by
Sierra Entertainment.
Unlike most of the
Real Time Strategy games that precede it,
Homeworld allows for movement of
units in all three spatial
dimensions. It features a song, also titled
Homeworld, by the progressive rock group
Yes.
In September 2000 a stand-alone expansion was released, Homeworld: Cataclysm[?].
