Lol, sure, ruin my fun

But, with major help from pyro_maniac, we have figured out the play balancing (necessary, as he's doing my demo mission

)
Anyways, China is basically crap, but they got numbers. EU is powerful, but their ships are highly specialized: I.E. an EU anti-fighter cruiser wouldn't be able to take on pretty much any other capital ship, but it will kick fighter's asses. The inverse is true, for, say, a destroyer: it can't kill fighters very well, if at all, but it can cut another cap ship in two.
US is jack-of-all-trades, master of none. Their ships are highly versatile, and even across the board, but, say, if a US anti-capital ship were to go up against an EU anti-capital ship, the US one would win. However, if a US anti-capital ship went against, say, an EU anti-fighter cap ship, or any fighter group, the US ship would come out on top, due to it's balanced weapons loadout. Also, the US weaponry is far more advanced, both in terms of homing, maneuvaribility, and hitting power, when compared to either China or the EU.
