There's an underlying plot. Rather than us playing the game from start to end of the war, we are generals (Or Admirals if you wanna be technical) in the overall armies of our chosen race.
Who the Vasari's enemy is is the biggest issue, but TDN bugs me.
TDN = Trader Defense Network (The other major theory is Trader Defense Navy, both are tied for followers but I prefer Network myself)
The Vasari's Enemy, as stated in the lore, is something of their own creation, and nearly destroyed an entire wing of the Dark Fleet, minus one ship.
I believe it was a result of their Nano-technology going berserk. What else could do that to the Dark Fleet, the veterans of the Vasari Army, without being equally damaged? How do you fight enemies the size of dust particles? just my own theory, nothing really to back it up, or the TDN thing for that matter.
