From the review by Nick Breckon of Shacknews:
"Sins of a Solar Empire is not Homeworld. It is not Galactic Civilizations. It is not Supreme Commander in space. It's a little of each, but then something else entirely.
I'm going to knock this game around a bit, but it will be a fatherly sort of beating, tough love with well-meaning intentions underneath the gruff, abusive exterior. Because I really do love Sins. It's a well-rounded, mostly-polished hardcore space strategy game for the PC. How often do you see that on a store shelf anymore? If the concept at all piques your interest, you will likely not regret a buy."
