I know it's kinda old news, but here's an interesting-looking title:
www.o-r-b.comIt's supposed to be one of the most MODable space games out there, and it's graphics r0xor!
But, being a die-hard Homeworld lover and veteran, I must say that it's almost
exactly like HW, except for new ships and [slightly] improved graphics.
Also, look down in the right-hand corner of this shot:

Is it just me, or does it say RU (Resource Units) and SU (Support Units)?
Also, it's got trails, which basically should be a Homeworld trademark, because that's what makes Homeworld (and HW:C), well, Homeworld!
