Just read about SGWP2.

Let me put some minds at ease. Singularity will not end up like that. Ever.
There is quite a bit of plot material available for Singularity, so the largest challenge (once I learn how to FRED aptly) will be plot pacing. And no, I will not resort to mere 'cool overload', by throwing ever more grandiose missions and scenarios at the player, because they inevitably turn into pointless BoE's. All capship fights have a purpose in the plot, and it's rare to see either side deploy anything larger than a cruiser, simply as 'reinforcements'.
Concerning Shivan fleets and supercaps:
The Shivans, because of the nature of the wormhole-gate technology they use to subvert normal subspace nodes, means that they can only transport a given mass through a wormhole until it collapses. They are very, very limited in the number and size of the ships they can transport. It took them nearly a year to open a large enough wormhole for a strategically self-supporting fleet - and this is a fleet of one Sathanas juggernaut, one supercarrier, a handful of destroyers, and supporting corvettes/cruisers. In the strategic scope, blowing up a destroyer is a huge loss, and it doesn't happen very often. Those two supercaps are absolutely critical to the Shivan war effort in GTVA space.
GTVA supercaps:
The pair of Colossus juggernauts were abandoned derelicts for a reason - they were engaged in combat, and the crews were forced to evacuate. Both are extremely heavily damaged - and over the course of two weeks, they cannabalize parts from one to get the (slightly) less-damaged one patched up enough for a trip through subspace.
The faction of Terrans from the distant, parallel future have a juggernaut in their entourage, but again, shock is only shocking when used seldom. It will only make in-mission appearances twice, since the ship is absolutely invaluable.
GTVA Destroyers:
The GTD Obsidian is definitely not the 'norm' among the GTVA destroyers. It is one of only four of the Raynor-Class, and it's the only one that is engaged in offensive operations, instead of being sidelined at critical GTVA worlds like the other three are. The Obsidian only shows up when something extraordinarily important is going on. Again, shock is only shocking when used seldom.
Although the GTVA has built quite a few of Hecates and Hatshepsuts, they are definitely not expendable. Destroyers almost always retreat before they take heavy damage, if possible. Securing a kill against a destroyer is not a casual or easy task, for either side.
Screenshots of more stuff, coming soon.
