CosmoGen is a premium cosmic civilization simulator where you guide life from its first fragile spark to an interstellar Kardashev Type-II civilization. Begin with a young planet, a microscopic species, and a universe full of uncertainty. As a cosmic overseer, your choices shape the destiny of an evolving civilization across deep time — from primordial survival to advanced technology, social complexity, planetary crisis, and the possibility of reaching the stars. Inspired by real scientific ideas, CosmoGen blends planetary physics, evolution, sociology, technology, and the mystery of the Fermi Paradox into an immersive strategy experience. Guide your civilization through major evolutionary eras, unlock powerful technologies, respond to world-changing events, and survive the Great Filters that may destroy advanced life before it becomes interstellar. Your civilization is not just a number. It has stress, harmony, inequality, trust, population pressure, technological ambition, and environmental limits. Every decision affects its future. Will you build a balanced society, push dangerous technologies too quickly, protect your planet, or risk everything for rapid progress? FEATURES • Guide life from microscopic origins to an advanced space civilization • Experience a procedurally generated planet with habitability, climate, resources, moons, axial tilt, and carrying capacity • Survive Great Filters such as solar super-flares, climate collapse, resource depletion, AI singularity, and cosmic disasters • Make strategic choices through scientific, ethical, and risky paths • Unlock a deep technology tree across Biology, Physics, Society, and Space • Manage population, energy, stress, harmony, technology, and social stability • Watch your civilization evolve through eras inspired by Earth’s deep history • Meet Lumina, an AI companion that provides contextual narrative and scientific explanations • Enjoy a cinematic interface with 3D planets, starfields, particles, aurora gradients, and frosted glass visuals • Designed with accessibility in mind, including dynamic typography, semantic colors, VoiceOver support, and high-contrast visual layers A SCIENTIFICALLY INSPIRED GOD GAME CosmoGen is built around one of the greatest questions in science: Why is the universe so quiet? The game transforms the Fermi Paradox into an interactive journey. Each civilization faces existential challenges that test its intelligence, ethics, resilience, and ability to survive its own progress. Some civilizations collapse before reaching the stars. Others adapt, transform, and rise beyond their home planet. Your choices decide which story will be written. AN EVOLVING COSMIC STORY No two civilizations feel exactly the same. Your planet, your events, your risks, your technologies, and your decisions create a unique timeline every time you play. CosmoGen is a strategy game, a scientific narrative, and a cinematic simulation of life’s greatest challenge: Can intelligence survive long enough to become cosmic?
