Space Sandbox vs Paleo Planet Sim

CREATE. EVOLVE. EXPLORE. Space Sandbox is the ultimate universe simulation where you play god. Create entire solar systems from scratch, manipulate gravity, and witness the rise of civilizations. BUILD YOUR UNIVERSE • Infinite Creation: Spawn over 50 types of celestial bodies—from burning stars and gas giants to black holes and mysterious gem planets. • Realistic Physics: Master the art of orbital mechanics. Create binary star systems and watch real N-body physics in action. • Terraforming: Transform barren rocks into lush, habitable worlds. Control temperature and atmosphere to support life. LIFE EVOLUTION Guide life through 9 distinct eras: • Microscopic Bacteria • Sea Life & Land Animals • Dinosaurs • Civilization (Early to Industrial) • Space Age: Watch your creations launch their own ships! MULTIPLAYER SANDBOX Explore the galaxy with friends! • Team Battle Royale: Fight for dominance in shrinking solar zones. • Space Racing: Compete in high-speed races through asteroid fields. • Co-op Building: Construct massive space stations together. FEATURES • Time Control: Speed up time to see millions of years pass in seconds. • Meteorite Economy: Harvest resources to unlock rare celestial objects. • 11 Star Types: From massive blue giants to tiny red dwarfs. • Orbital Mechanics: Set realistic orbits with barycenter physics. • Temperature System: Heat planets to create habitable zones. • 6 Game Modes: Battle Royale, Deathmatch, CTF, Racing, Survival, Exploration. • Character Customization: Design your own space explorer. • Stunning Visuals: Beautiful 3D graphics optimized for iPhone and iPad. The universe is in your hands. What will you create?

Build a planet. Run its climate. Watch its weather. Paleo Planet Sim runs real research models on worlds you design. Two divisions, read off your settings: Earth-like keeps the sun, the greenhouse, the tilt and the day length inside what Earth itself has been through; push any of them past that and the planet is Extreme, everything the model can survive. Each slider shows where Earth's range ends, the app tells you which division you're in before you launch, and you can lock either one. Set the sun, the greenhouse, the tilt, the length of the day and the depth of the ocean, then pick a geography: Earth, Pangea and other ancient Earths, an all-ocean world, a supercontinent, or paint your own continents with the terrain brush (Apple Pencil supported). Launch it and a real climate model runs 45 simulated years in the cloud while you do something else. You'll get a notification when it finishes, usually in 1.5 to 3.5 hours. Explore the result on a 3-D globe: temperature, biomes, terrain, snow and rain, month by month, with a magnifier to read any spot. See the records your planet set, its climate charts and maps, and compare any two planets side by side. Then make weather. Pick a moment from your planet's own history and run a real weather model for 5, 10 or 15 days. Watch clouds, rain and snow, wind, the jet stream and tropical cyclones move across your globe and map. Every valid planet is ranked on the leaderboards, with gold, silver and bronze for each record. Time-limited challenges set one goal, one deadline and in-app prizes. Looking is free: spin the reference planets, play their forecasts and browse every board. Runs use credits. You start with 5; a planet is 1 credit and a forecast is 1 per 5 days. Prices are always shown before you launch. Made by a PhD atmospheric scientist.
