I do have to agree with X-Play with regards to the campaign. I love the game, it's incredibly addicting, but single player skirmishes get a bit repetitive, especially as the AI tends to use the same strategy every time (Get a big fleet, camp out a wormhole, and send a large siege-only fleet to attack me). I loved looking up the backgrounds on the three races before and after the game was released, but I was disappointed to find that those stories were relatively insignificant to the game, other than to say "This is why this race is here." It's kind of a tease to say that the Advent are searching for their lost homeworld and that the Vasari are fleeing from a mysterious force of their own creation which is destroying their entire empire, yet not include these plots in the game! Will the Advent find their homeplanet? Will the Vasari ever discover exactly what creation of theirs is hunting them to extinction? Will the TEC reconcile with it's past sins?
The title of the game is a reference to the sins that each of these races have committed in their past, the TEC's banishment of a foreign culture, the Advent's strange practices and unchecked thirst for vengeance, and the Vasari's oppressive rule over their lost galactic empire, and I was hoping that there'd be a story where each race came to face the sins of their solar empires.
I love the game regardless, just it could've had so much more!
