I'm after a bit more development before I bunker down. I just joined a trade circle and my income shot up to 3.2 mil/ day post bills, so I think I'll get an Interstate. Thanks for the advice.
One more thing, my fleet's costing me $ .26 million/day, which over time is quite some chunk of change. I don't see any new Great War brewing on the horizon, and with nukes for defence I see no reason to keep the ships on hand. Is there any real reason not to mothball them, enlarging my warchest to rebuild whenever CN diplomacy goes 1930s- style again?
