OBSERVE: A World That Plays Itself

Watch entire civilizations rise, war, and fall across a 3,400-region map, then shape the outcome however you like. Build the world in the editor, reach in and command it like a god, or go deep and program the AI that runs the nations. Set it loose and watch your world unfold, or take your strategies to the Arena and pit them against everyone else's.

Watch It Unfold

Observe is a world you can leave running. Nations expand, ally, betray, and collapse on their own across a seamless, world-wrapping map drawn from real geography. Sit back and watch history happen, or steer it whenever the mood strikes.

• Endless Mode. Flip the toggle and every time a game ends, a brand-new shuffled world is generated and play continues forever. Set it running and let civilizations rise and fall while you work, watch, or relax.

• A living map. Read the whole world at a glance through map modes for alliances, wars, and the shifting balance of power.

Scenario Editor: Build the Board

Design the worlds you watch and fight over.

• 3,400+ regions across a detailed, seamless, world-wrapping map.

• Alternate histories. What if Rome never fell? What if the Mongols rode again? Take full control over countries, populations, borders, technology, and starting conditions.

• One-click Randomize. Hit the button and get a fresh, shuffled world to set loose. Instant new challenges, no setup.

• Save your favorites. Build a library of custom civilizations and drop them into any scenario.

• Share your worlds. Build the scenario you've always wanted to watch, then hand it to everyone else.

God Controls: Reach Into the Sim

It's your world. Reach in and meddle. God Controls let you intervene in any running simulation directly: tip a war, prop up an underdog, or unleash chaos, all through an in-game HUD. Watch a situation unfold, then change it with a click.

AI Studio: Go as Deep as You Want

Want more than a spectator's seat? You can write the minds the nations think with. Observe ships with a built-in code editor running MiniScript, a clean, readable scripting language for authoring AI doctrine: when to expand, who to trust, where to mass its armies.

• Never written code before? A 30-lesson interactive tutorial takes you from your first line to a working war machine, in-editor, at your own pace.

• Already a programmer? The API exposes composable primitives (full enemy intel, army allocation, front objectives, economy) and gets out of your way. The strategic ceiling is yours to find.

• Iterate fast. Run any scenario right inside the editor, watch your script command nations live, tweak, and run again.

The Arena: Script vs. Script, Ranked

Wrote an AI you're proud of? Prove it. The Arena pits your scripts head-to-head against other players' creations in 1v1 duels and a global, properly-rated ELO ladder.

• Spar instantly. Load a script, pick any rival on the ladder, and watch the duel play out live before your eyes.

• Climb the ranked ladder. Matches are rated with a true round-robin system, not luck-of-the-draw ELO. Each of your named AIs earns its own place on the board.

• Run up to 3 AIs. Field different doctrines and see which one the meta rewards.

Watch a world play itself. Shape it however you want. This is Observe.
