I know it's probably a little late in fs2's life span to start a new campaign that has a chance of being good quality, and being finished, but I'm thinking about trying.
It takes place roughly 20-25 years after Derelict (such a good campaign I couldn't help but make it part of teh background). Here goes:
After the Shivans were trapped in Capella, the GTVA began rebuilding their fleets. Because of lack of money, Command couldn't afford to recreate all of the high-end fighters lost in the nebula. Our fleet technology regressed several years. Fleets were constructed of Leviathan and Fenris class cruisers, Hecate class destroyers, escorted by Myrmidons, Valkyries, both Hercs, and Medusa bombers. Artemis bombers, Perseus interceptors, and other powerful fighters were nowhere to be seen.
We were getting somewhere technologically though. GTVA scientists discovered a host of new systems, and by the time the campaign starts, we have doubled known space.
Eventually, the GTVA began gaining enough money to start production of Deimos class corvettes, Artemis bombers, and Erinyes class fighters. Because the GTVA had money, and pirates didn't, piracy went down in GTVA space; as pirates could only afford Apollos and Ulysses.
The Capellan refugees were located and relocated dozens of times. Eventually, Command decided to start colonizing the new-found worlds, nicknamed the Border Worlds. Arcturus became the center of trade for these new worlds. As they became more and more independant from aid from the GTVA central systems, they began building a large military force without GTVA central command approval. Eventually, GTVA officials found out, and threatened to fine them if they did not distribute their built warships around the fleets.
They continued to build warships, and the GTVA threatened to take military action. The Border Worlds did not respond. The GTVA sent a cruiser into Arcturus to investigate, and it was destroyed by a squadron of Osiris and Medusa bombers.
This is the story of Border Worlds fight for independance from the GTVA. The Borderworlds systems are: Tau Sigma, Tania Australis, Tegmen, Delphi, Kaus Borealis, Mintaka, Gienah Cygni, and Enif.

All other systems are GTVA.
I am trying to learn to model, but I might need some help. I'm planning on having a few new ships. Like, one Terran and one Vasudan space superiority fighter, a new light cruiser, and one new freighter.
As for FREDing...I will need lots of help on that, as I can't FRED very well (out of practice).
So, what do you think? Worth anything, or will it die before it can get anywhere?
