Long Live the Confederation!
250 million is wrong, but the Hornet (and the other Wing Commander I ships) do cost "over a hundred million credits" (per the conversation with Halcyon when you eject.)
Well, that one could be explained by market forces...economic depressions are not uncommon after major wars historically (and the Nephilim War sounds like it was particularly harsh on infrastructure), and if there really was that much surplus material (enough that Confed could afford to privately sell massive battlecruisers), well......Yes, and I suppose the fact that post-war prices are still low (in Star*Soldier) argues against it being some kind of wartime subsidy.
Well the Tri-System has a big piracy problem and the government pays bounties for shooting down pirate spacecraft. There isn't even a black market for ships because even criminal sources virtually can't beat the official prices (we learn that in the very beginning of the game).Privateer 2 is also telling; it's a different economy but it has the same issue... and there's no ongoing galactic war that the government would be subsidizing.
