Earth Sandbox vs Grainfall

Earth Sandbox is an experimental simulation game centered on Earth itself. Instead of following a fixed story or objective, the game invites you to explore how a planet reacts when its core systems are changed. Climate, gravity, oceans, and atmosphere interact dynamically, creating unique outcomes every time you experiment. You can adjust environmental conditions, trigger natural events, or push the planet into extreme states. Rising temperatures may reshape ecosystems, shifting gravity alters planetary balance, and sudden disasters can permanently change the world you observe. Natural events such as meteor impacts, earthquakes, volcanic activity, and global climate shifts are part of the simulation. Each event influences the planet differently depending on existing conditions, encouraging experimentation rather than repetition. The simulation is driven by interconnected systems inspired by scientific principles. Population trends, environmental stability, and planetary conditions evolve in real time, allowing you to observe long-term consequences of your actions. Features: • Earth-focused environmental simulation • Interconnected climate and planetary systems • Dynamic natural events and long-term world changes • Real-time population and ecosystem trends • Interactive tools designed for experimentation • Clean visuals with intuitive controls How will your choices shape the future of this Earth?

Grainfall is a falling sand toy. Pick a material, drag across the screen, and watch it react with whatever is already there. Sand piles up and slides back down. Dig a hole and water will find it. Oil floats on top of water, and oil burns. Plants drink from standing water and creep toward it. Fire spreads, leaves ash behind, and boils water into steam that drifts up, cools off, and comes back down as rain. There is no score and nothing to unlock by playing. What you get is twelve materials that all react to each other, and the fun is working out how. Build a glass tank and fill it with acid, since glass is the one thing acid cannot chew through. Pour lava into water and it sets into stone. Light one end of a gunpowder trail and follow it along. Hit record at any point and Grainfall turns what happened into a video, with sound built from the same events you just watched. Save a world and it keeps a picture of itself in your list. Send one to a friend as a small file and it opens straight into their copy.
