SteamAbout MMOS: MMO Simulator
You run the MMO. They play it.
Most games put you inside the MMORPG. This one puts you in the chair behind it. You are the studio, the live team, and the world designer all at once: you build the zones, stock the dungeons, author the loot, set the prices, and open the systems. Then you step back and watch thousands of fully autonomous adventurers move into your world, form parties, grind levels, chase gear, haggle on the auction house, die to your monsters, and — if your world is good enough — keep paying the monthly subscriptions that fund everything you do.
It's SimCity meets WoW, with a pinch of RollerCoaster Tycoon: a top down living-world management sim where every subscriber is a simulated player with their own goals, and your job is to build a world worth playing.
The core loop
A world that actually plays itself
The adventurers aren't scenery. Each one is an autonomous agent with a personality built from a weighted blend of player-type drives — the killers, achievers, explorers, socializers, and the gold-obsessed traders. Those drives shape what every adventurer chooses to do moment to moment:
They form parties, share threat in combat, level up, gear up, go broke, get rich, and occasionally die — all emergently, all driven by the world you built. Click any adventurer to read their thoughts, see their drive profile, inspect their gear and professions, and watch their personal story unfold.
Deep authoring tools
A real, self-correcting economy
Gold isn't a number that only goes up. The simulation models faucets and sinks: monsters mint gold when looted, while vendor purchases, flight fares, and auction deposits drain it back out. Item prices are world-derived from each item's identity and quality, then nudged by live supply and demand. A built-in economy dashboard tracks gold minted vs. burned (with per-source breakdowns), population, wealth leaderboards, and XP rates over time — so you can spot inflation, dead content, or a broken market and fix it.
Tune everything
A sandbox tuning layer lets you adjust the rules of your world, and a seeded simulation means you can reproduce and experiment with worlds deterministically. The whole thing runs as a living, headless simulation under a stylized, flat illustrated art style — readable, colorful, and built entirely from programmatic visuals and synthesized audio, with a day/night sky cycle overhead.
Genre & style
If you've ever finished a raid and thought "I could have designed this better," this is your chair.
