Or is it just another game nothing alike with sins

Sins doesn't have to worry, but GalCiv, and to a lesser extent Sword of the Stars, does. GalCiv is showing its age and but for it's excellent planetary development model, would be completely forgettable.
If anything, this game reminds me of Stars! more than any other game. If that is the case...I will be very happy! 
BTW: I did an interview with Bob Smith back in September about this game. Seemed promising them and even more so now!
