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?

Gravity OB1
Read full descriptionHide full description
GRAVITY OB1 turns orbital physics into pure arcade thrill. Sling your ship across a living solar system, ride the pull of planets and black holes, and master gravity itself — because the radar is your only map. THREE GAMES IN ONE - CRUISE — Pure flight. No weapons, no boosters. Just you, gravity, and one perfect slingshot to the target. - COMBAT — Full war. Dodge mines, missiles, and asteroid lasers. Boosters and shields at your side. - ASSAULT — Take the fight to the enemy. Dogfight alien ships with a twin-stick control scheme, lock into orbit around planets, and rain fire on your foes. MASTER GRAVITY Every shot is a puzzle. Planets bend your flight path, black holes swallow the careless, and the sun is always hungry. Learn to read the pull, thread the needle, and let physics carry you home. ORBIT LOCK Fly close to any planet and lock into a stable orbit — circle your target hands-free while your cannons and homing missiles pour fire into it. A gravity-powered gunship run like nothing else on mobile. A FLEET OF SHIPS Unlock 8 distinct ships, from the nimble Needle interceptor to the mighty Bastion battleship. Each flies differently — light and fast, or heavy and armored but harder to pull free of gravity's grip. 100 MISSIONS + SUPER NOVA Ten levels across every mode, each with escalating hazards: moving asteroids, black holes, orbiting worlds, and finally the endless waves of Super Nova. FEATURES - Real gravity physics — no two shots ever feel the same - Three completely different game modes - 8 unlockable ships with unique handling - 8 alien enemy types with distinct behaviors - Homing missiles, cannons, boosters, and shields - A tactical radar you'll learn to live by - Premium hand-crafted art and an original soundtrack Free to play the opening of every mode. Unlock the full campaign once — yours forever. Slingshot in. Master the pull. Clear the system.

Verdict
The clearest difference is in-app purchases: Earth Sandbox at none against Gravity OB1's 1. Gravity OB1's advantage is ads (none vs shown) and iOS requirement (13.4 vs 15.0). On price, update cadence and device support there is nothing between them.
