Guys, seriously. Shivan ships aren't that much better than Terran/Vasudan ships, and you kill A LOT of Shivans in both games. Yeah, we're outnumbered and outgunned, but I think it's by a comprehensible amount. If they were II or higher they'd just steamroll over us without a second thought. Type III and they could instantaneously vaporize all of our solar systems just as easily as we would swat a fly.
That said, I have had visions of venturing into Shivan space with some kind of amazingly advanced fleet, then watching Shivan ships in the distance a thousand times bigger than your fleet, duking it out with equally colossal ships of some other race ("symptom of a bigger problem" and all that). It would be great to just sit in awe of some massive conflict so destructive you couldn't begin to approach it without being destroyed.
Also, where does the GTVA fit on that scale? 1.01? 1.1?
