Are there any spaceship rts style games?

Okay ive played sins of a solar empire, star wars empire at war, stargate empire at war (Mod), supreme commander 1, 2, and Forged alliance, age of mythology, Age of empires series, Perimeter, stronghold legends / crusades, Empire earth, universe at war, starcraft 1 and 2, and many other rts style games. I would like to know if there are anymore good ones out there. I like to play on LAN with friends at times, and enjoy games like the ones listed above. It would be greatly appreciated if there was a fun game out there that i haven't tried yet, and is worth a try.
