Stardock, mainly a name famous for their desktop enhancement products rather than their games, have today launched the forth phase in beta testing for their sci-fi real time strategy, Sins of a Solar Empire. The game seems to have some rather complex mechanics judging from some of the posts on their forum, yet the only way to access the beta test is to pre-order the game, which is slightly annoying, as personally I'd love to try it out, but not to pay and all.

Anyway, check out the forum topic here.
