There is one word, and only one word that can describe the nature of the campaign:
TERROR
That's right, the campaign is terrible (terrifying? did I misuse this word wrongly?) for many reasons:
1) Many of the goods races have been destroyed utterly by the Drengin: Torans, Drath, Arceans, Korx ... all farmed for food by the Drengin. Extreme TERROR.
2) When the Terrans returned on maps 2 and 3, all of the races have turned against the Terrans, forsaking their past alliances, and have used TERROR against the terrans.
3) When the shield on earth was finally brought down, the crusade will go on to instill a new sense of TERROR to the universe.
Do you all feel the same way that I do, that the campaign is terrible?
