Stardock has announced that an all-inclusive collection featuring its fab Windows-based 4X strategy title Sins of a Solar Empire, its first expansion, Entrenchment and the upcoming Diplomacy expansion will release on February 9 for $39.99. In addition to availability on Stardock's own Impulse digital distribution service, the set will make its way onto shelves across the US in something called a "box."

Anyone who pre-orders Sins of a Solar Empire - Trinity via Impulse will get instant access to the beta version of the Diplomacy expansion, which seems like a good strategy to us.
