I guess Homeworld 2 should also be on the list over there. I got it pretty cheaply somewhere and played through the campaign, but unistalled it after I had beaten it. IMO, while it does give you the general gamestyle feeling as Homeworld, there just isn't enough new features to make the sequel feel like it is actually innovating instead of just Homeworld with updated story. (Also, the fact that you have to jump right after finishing a mission is just awful....I want to be able to rebuild my army to prepare for the next mission.....the Garden of Kadesh missions come to mind here from Homeworld)
