With the first add-on pack for Sins of a Solar Empire arriving in just under a month, publisher Kalypso Media has announced that three more add-ons are on their way as well. Gamespot has an early look at the first add-on, Entrenchment, and a couple of additional screenshots are available at Shacknews. The game's creative director, Craig Frazer, also explained their reasoning for making small expansions rather than large ones: "If PC gaming is to survive, the industry will need to be open to change. We went out on a limb with our anti-DRM stance and it paid off really well. We tried an unusually long beta period and that worked as well. Micro-expansions are just another experiment we are trying out to improve the market. These small expansions give us the opportunity to provide highly focused, high quality content within a reasonable time frame. Micro-expansions also reduce the development risk associated with 1-3 year cycles. With lower risk, we can be far more progressive in terms of gameplay and content."
