In addition to Warhammer 40,000 Dawn of War, Homeworld 1/2/Cataclysm, Freespace 1/2/Silent Threat, I have to offer X3: The Reunion.
The latest and greatest Elite/Frontier clone. I think they had massive bug problems with 1.0 but they've swiftly fixed them Im led to believe. (nothing like an EA debacle)
UFO: Aftershock is the latest in the UFO/X-Com series. You may have trouble finding it in the US for a while, as like X3, its a European developed game and damn we do they good when we actually do them
