@Raroun Homeworld (1999) was revolutionary. A full third dimension to master in a real-time space strategy game, ballets of fighters, original missions, a strong visual style supported by a moody soundtrack, it had everything.
Homeworld 2 (2003) mainly kept the visual style and ditched the third dimension altogether which made it more accessible. Homeworld: Deserts of Kharak (2016) is surprisingly similar to Homeworld 2, despite happening on land, because of the same missing third dimension. Neither are bad games, but they kind of pale in comparison to their elder.
