Once Upon The Universe — Steam game overview

Stored observation / content update: 2026-10-26T04:55:38.000Z

Once Upon The Universe is a god-game that takes you to the VERY beginning of creation. You begin the game just seconds 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.
