Unending Galaxy is a 2D sandbox/simulation/4X space game for Windows. As a player, you can fight, trade, explore, build factories, and form your own empire. There are multiple alien factions living in the same universe as you, and, as empires, they are able to conquer territory and conduct diplomacy. The economy of each empire influences its military production and capacity. The game also has a procedural mission generator. Most missions are generated based on what’s actually going on in the galaxy. For those who are familiar with the X-Universe games, this is a similar game concept-wise but with a much more dynamic universe. A detailed feature list is available.
