Once Upon The Universe is a game tagged God Game, Space Sim and Sandbox by Paweł Witkowski ByteEncode, released May 29, 2026. It has 37 Steam reviews (Positive). The Steam games most like it include X: Tension, Unending Galaxy and Biosphere Simulator.

Once Upon The Universe is a god-game that takes you to the VERY beginning of creation. You begin the game just after the big bang, with nothing but an empty space and a lot of super hot hydrogen in the entire universe. Fill the universe with life and watch it thrive - or destory it.
