The
Gratuitous Space Battles Website announces plans for an expansion that will add new campaigns to add some context and remove some of the gratuitousness in the strategy/sim/management space combat game. Word is: "The game will not care if you have any earlier DLC or not. If you do, you will face fleets built from those extra races, but if not, you just get enemy fleets built from the original 4 fleets." Here's a bit more:
The GSB campaign is a singleplayer 'conquer-the-galaxy' style game, where you build up vast space fleets and kick interstellar ass. Rather than set, pre-determined fleets to battle against, the game utilises the fleets designed by other GSB players to provide an endless variety of opponent, so you will be pitted against real carbon-based intelligence on every step of your path to galactic dominance. The GSB campaign is not a full 4X game, but a contextual 'wrapper' for GSB that introduces new strategic concerns such as crew and cash shortages, repairing ships between battles, the need for construction and repair facilities, and the ability to issue a retreat order mid-battle.
