MMOS — the MMO Simulator

Time control to watch weeks unfold in minutes
You're not the hero.
You're the company behind the game.
In every other MMO, you log in and grind. In MMOS, you sit on the other side of the screen. The dungeons, the economy, the flight paths, the late-night raids — you make all of it, then the players arrive on their own.
Think SimCity meets World of Warcraft, with a pinch of RollerCoaster Tycoon. Your rides are raids. Your citizens are subscribers. Your bottom line is whether they renew.

Everything a real MMORPG needs — and you run all of it
MMOS simulates the systems that make an MMO tick. Each one is a lever you pull to keep your server alive and growing.
The Living Server
Thousands of autonomous adventurers log in, set their own goals, and keep your server alive — or quit on you.
Learn more🏝️Build Your World
Paint islands tile by tile, raise terrain, and place the towns, inns, docks, and graveyards your players depend on.
Learn more💰Economy & Auction House
A real player-driven economy with vendors, an auction house, and gold faucets and sinks you can actually read on a chart.
Learn more⚒️Professions & Crafting
Gathering and crafting professions give adventurers a second career — and feed raw materials into your economy.
Learn more⚔️Archetypes & Combat
Tank, damage, healer, support — adventurers take on roles, form groups, and tackle the mobs you seed across the map.
Learn more🛡️Factions & PvP
Rival factions, contested zones, and player-versus-player conflict turn a quiet server into a rivalry worth subscribing for.
Learn more🦅Travel & Flight Paths
Docks open sea routes between islands and flight paths stitch your world together so adventurers can reach the content you built.
Learn moreFrom empty ocean to thriving server
The loop is simple to learn and deep to master.
Build the world
Paint islands, raise terrain, and place towns, inns, docks, and graveyards. Every tile is a bet with your starting capital.
Open the servers
Autonomous adventurers log in and start playing the MMO you built — hunting, grouping, crafting, and sailing on their own.
Keep them subscribed
Read your KPIs, fix what's broken, and grow a world worth paying for. Bored players cancel; happy ones bring friends.
