I'm looking for a space RTS, in the the style of the homeworld series. I've played both, and liked them quite a bit. Any recommendations?

Starmaggedon isn't bad if you can get it working properly, but apart from that, there aren't too many 3D space rts's out there :(

Nexus: The Jupiter Incident and perhaps Haegemonia - Legions Of Iron. The later had good gameplay, but horrible voice-acting and a rather mediocre and cliché storyline. Nexus, on the other hand, is a really good game. Try looking up some reviews.

I liked Haegemonia overall, it was comparable in quality to Homeworld2, better in some of the strategy aspects IMO, not as good in the combat. I like the complexities of planet management, the way they implemented the equivelant of hero's, the way you're forces gained experience. Overall, if you Homeworld I think you'll like Hegemonia.
