MMOS: MMO Simulator

Build the MMORPG you've always wanted to play. MMOS is a single-player management game where you build a fantasy MMO and run it for a population of simulated adventurers. Create the world they explore, the classes they play and the loot they chase. Their subscriptions fund your game, so give newcomers a good start and veterans a reason to stay.

Build islands, lay roads and create towns. Fill your zones with monsters, quests, gathering spots and places to rest. Decide where adventurers begin, what challenges they find along the way and which rewards wait in the dangerous corners of your world.

Lay out rooms, place enemies, give bosses their abilities and choose the loot. Send a test party through before opening the doors, then watch adventurers gather through the group finder and tackle your creation. Follow the fight, inspect the results and adjust the challenge. Build small-group dungeons and arenas, or raids and battlegrounds for larger group content.

Design classes with tank, healer, damage and support roles. Give them spells, pets and shapeshifting abilities, then watch those builds fight your monsters. Create weapons, armour, crafting recipes and quest rewards. Put a rare mount on a boss's loot table and give collectors something to chase.

Some adventurers want better gear. Others spend their sessions gathering, trading, exploring or socialising. They make friends, join guilds and form parties. Follow a favourite character, inspect their equipment and read their thoughts to find out what they enjoy and what your world is missing.

Adventurers gather materials, craft equipment and trade through the auction house. Set vendor prices, tune rewards and see how your decisions affect supply, demand and player wealth. Track subscriptions and server capacity alongside the in-world gold economy, and use your reports to decide where to invest next.

Start with ready-made content or create your own. Unlock more tools through research, customise your sandbox settings and schedule events on the calendar. Export your creations as Content Packs to share with other players or bring into your next world.
