Nice idea -
Two alliances, alliance shared resources and victory conditions based on collecting material and through PvP action - pretty solid concept.
Maybe I read it wrong, but looks like the material (PUC) is only required to be carried on the ACE ships? Makes more sense for all ship building to require it, so when you build ships you deplete the material thats stored.
Also, you could have it being recovered from salvage after a successful attack rather than being required to capture the ships - means its a unit of success from any attack - less random.
Actually, what I meant is yes, salvaging resources from pvp. I just said it used to power ACE ships, but they get it from corpse processing, I did not mean actually capturing ships for it. On second thought, capturing should give more, less is destroyed in explosion...
