What is One Deck Galaxy?

This digital tabletop strategy game takes place in Insula, a distant region of the galaxy. You combine a homeworld and society, then roll and assign dice to establish colonies, develop technology, launch probes, and build fleets. Your civilization confronts an adversary with its own rules in standalone sessions or a six-game campaign with ability upgrades.
