I think I'll stick with the low-density, ultra-high-temperature plasma beams; sufficient to whack fighters and bombers around. Otherwise, I'd end up with the problem of cruisers getting shoved around at insane speeds by the juggernaut-grade beams (BFRed, BFGreen, BFVas).
Also, the single-mission-release demo is actually going to be a demo to the seven-mission demo later on, largely because I have limited FRED experience. It's really going to be more of an alpha-release teaser mission.
On another note, how many destroyers could the GTVA build within roughly a decade? What starship-building capabilities did they have in the Capella era? The GTD Hecate (especially the modified version, with extra beams and upgraded armor) caught on very well with the GTVA security council, as did the Hatshepsut - so they've been churning them out as quickly as they can manage.
They also have a handful of 'new' destroyers - the Vasudans get the Apophis (forward plasma beam artillery via single BFVas), and the Pharaoh (enormously, massively, over-armored carrier). The Terrans get the Titan (of course, a carrier ship, but fast, agile, and with great forward firepower), and the Raynor (omnidirectional beamrape platform with massive armor).
Now, using the reference in BP: WiH as a guide - when one character said (referring to a Hecate): "I can't believe the Tevs have two dozen of these." And this is from the Terran-side of the BP-verse, which pretty much suffered the economic apocalypse after Capella. Add in the few Orions left over, and a seldom few Titans and Raynors...and it's quite possible that the Terrans had about 30 destroyers.
Without that catastrophic Terran-side economic meltdown, is it possible that the Terrans could be running 100+ destroyers? I'm a bit concerned that having four Raynors, even under these circumstances, might be too many - they're exceptionally rare and expensive.
