Halo would be neat.
Spartan games have produced a space ship combat of Halo.
+1 Babylon 5. A lot of factions.
+1 Battlestar Galactica (They do have a lot of ships instead of what I have heard, and they have a lot of new invented ships old and new era)
+1 Star Trek. Without fighters.
+1 Buck Rogers. I know, just the draconian and the earth protectorate, models just for two waves of ships...
Yea But I am not sure about with what i have heard of their previous space combat rulesets.
A lot of that is probably not really accurate. The 1st edition of Firestorm had some flaws, but tbh the latest one is very good.
