Sins of a Solar Empire is without a doubt one of the favorites of all PC realtime strategy fans. On its website, the publisher of the game, Stardock, let know the game would receive another mini-expansion next year. This would be the second time the game gets added to, the first expansion being called Entrenchment, this new expansion will be dubbed Diplomacy.

As the title suggests the upcoming expansion will focus mainly on diplomacy and will give players more options to conquer the galaxy in a peaceful way. The game will see a Q1 2010 release, with a beta phase to hit home this coming fall, so a little bit of patience is in order.

Considering Entrenchment cost around $10, it is expected also Diplomacy will sell for about that price.
