Gaia

Gaia is an incremental game about creating life across the universe. You begin as a nascent being focused on a speck of rock in an empty sea of blackness, with the ability to create life. You seed worlds, study your creations and use what you learn to help life survive on hostile planets.

Life and research

Life is difficult to create, fickle and short-lived, but it persists. You research your creations to learn how they survive, then introduce those methods to new worlds. Evolution and extinction are central to the game, alongside biology concepts including symbiosis, sexual reproduction, genetics and predation.

Numbers and planetary limits

The game changes how counting works: its number base shifts with the complexity of life at a given time, rather than staying fixed at base 10. Each planet also has a carrying capacity that limits how high its numbers can grow. To count to higher values, you need to expand life's reach.

Explore other worlds

You can explore nine planet types, each with its own challenges and strengths. Each also holds secrets that take multiple visits to uncover, using knowledge gained elsewhere. The game offers 40–50 hours of gameplay, or 10 hours with substantial offline progression.
