Thanks for the responses, people!
I was just wondering if a particular race had a "racial" technology" that gave better ship weapons and defenses than those available with a "maxed out" Terran tech tree. I could have phrased my title better (sorry!)
So, no Dread Lord ships (not surprised). Is there any way to get precursor rangers?
Thanks for the note about "war of the gods". I'll check it out.
