Beyond that, in keeping with the overall approach of the entire game, each of the three races has their own unique approaches to diplomacy. Near the top of each faction's research trees is a technology that eliminates any racial penalties that might dampen negotiations. All factions have three levels of basic relations to research, which can give them slightly better results when negotiating. To get to the heart of the new expansion, players will really need to dive into the new Diplomacy tech tree. We've had a build in our hands for a while now and are definitely looking forward to checking out the full release. This is still a game about war, of course, so you won't be using Diplomacy to win a democratic sort of victory, but it does allow for lots of manipulation of both your allies and your enemies throughout the course of the game.
Called Sins of Solar Empire: Diplomacy, the new expansion will greatly improve the diplomatic options available to players. Later this month, Stardock will release the second and final micro-expansion pack for Sins of a Solar Empire.
