MMOS: MMO Simulator

From the Devs

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 RollerCoaster Tycoon with an MMORPG twist: 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

• Build the world. Paint terrain, carve zones, lay roads, plant the wilderness, and place the monsters, towns, and points of interest that give your MMO a shape.

• Stock the content. Author monsters, loot tables, gear, consumables, quests, and gathering nodes. Decide what drops, where, and how rare it is.

• Run the economy. Open vendors, an auction house, and a flight-path network. Set fares, prices, and policies. Manage the flow of gold so your world stays healthy instead of inflating into chaos.

• Grow your playerbase. A good world attracts and retains subscribers. Happy players tell their friends; bored ones churn and tell everyone why. Watch the population, the gold economy, and the XP curves, then tune the world to keep adventurers happy and paying.

• Run the live game. Schedule events, follow the seasonal calendar, open new dungeons, and react to what your players actually do. Retention is won patch by patch.

A world that actually plays itself

The adventurers aren't scenery. Each one is an autonomous agent 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:

• Levelers push into tougher zones as they outgrow the easy mobs.

• Treasure-hunters farm monsters for their most profitable drops.

• Gatherers learn professions and work resource nodes.

• Traders buy low and sell high on the auction house.

• Explorers spend real gold on flight paths to see the far corners of your map.

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.

A society, not a spreadsheet

Adventurers make friends, chat, hang out in town between sessions, and found guilds with rosters, roles, and banners. Loot gets rolled for need or greed. Streamers show up, spotlight your content, and pull in waves of new players. Click any adventurer to read their thoughts, traits, drives, and current wants, inspect their gear and professions, and see exactly why they are delighted or about to quit.

Deep authoring tools

• Terrain & zones: paint grass, water, roads, and hazard tiles like lava; define polygon zones with their own identity; plant trees and decorate the wilds.

• Monsters, Dungeons & Spawners: author creatures with stats and loot tables, then place spawners that keep your zones populated. Build intricate dungeons or raids for players to group up and explore in.

• Classes, Abilities & Gear: design classes, abilities, weapons, armor, and offhands with level requirements, two-handed rules, and combat-stat effects. Every item has a quality tier from common to legendary that drives both its power and its rarity on the avatar.

• Mounts: a collectible roster of ground and flying mounts that adventurers save up for, show off, and ride across your map. Set them as rare boss drops and watch your most dedicated players flaunt them.

• Crafting, consumables & quests: gathering nodes, crafting stations, recipes, potions, and quest content for your adventurers to chase.

• Factions & PvP: set up rival factions, balance their populations, and let the conflict play out.

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, mounts, crafting reagents, bank vault slots, 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. You set the subscription price, and every design decision echoes in the ledger.

Dungeons: design, test, open

Dungeons are content you operate, not just place. Lay out the rooms, pick a theme, stock the bosses and telegraphed abilities, then send staff testers through before opening day. Once the doors open, adventurers queue through the group finder, clear it or wipe, and leave ratings that drive future demand. A dud sits empty; a great one becomes the reason people subscribe.

Tune everything

You don't start with everything: new systems, capacity, and content unlock through a research tree, growing a small game into a full MMO. 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, self-directed simulation under a stylized, flat illustrated art style - readable, colourful, and built entirely from programmatic visuals.
