Universe999999

Universe999999 is a universe-building game centered on decisions, trade-offs, management and expansion. You shape a universe whose cosmic formation and structural evolution take place beneath the surface, while your choices bring responsibility and consequences.

The project began as an experiment in simulating a universe from the Big Bang, with the four fundamental forces governing how matter, energy, stars and structures emerged. Its focus has since shifted from watching the universe take shape to making the player’s choices matter, with philosophical questions also informing its design.
