I just came across this interview with Ironclad’s Blair Fraser with 1up.com about the next installment in the micro-expansions for Sins of a Solar Empire.
"The second micro expansion is really about both diplomacy and the non-military aspects of the game which will bring it more in line with the RT4X sub-genre we've labeled it as. Certainly, multiple paths to victory, especially non military paths, are part of that," Fraser said, adding that the introduction of additional game modes that will make the game more multiplayer-friendly is also a distinct possibility, pointing to the user-made Sins of a Solar Empire DOME mod as an example.”
