The folks at GameSpy were able to give Sins of a Solar Empire: Rebellion for a quick spin, and they have posted their preview with their initial impressions.
“The model for the space combat in Sins of a Solar Empire was the Battle of Endor in Return of the Jedi, says Ironclad co-founder Blair Fraser. "We really wanted to have that feeling of the Star Destroyer flying overhead, where you can see all the little details." Sins got pretty close, and thanks to an engine overhaul, the stand-alone expansion Sins of a Solar Empire: Rebellion is getting even closer. In the version that Fraser brought by to demonstrate what Ironclad's been up to lately, textures are considerably sharper and more detailed when viewed up close, huge Super Star Destroyer-sized Titan ships cast dark dynamic shadows over their prey, and enhanced particle effects make the battles even more fun to watch.”
