An MMORPG (Massively Multiplayer Online Role-Playing Game) is an online role-playing game in which thousands of players share a persistent virtual world. Characters level up, collect gear, complete quests and cooperate or compete with one another.
Why it matters
The world keeps running when you log out, so state such as character data, inventory and economy must be stored centrally on the developer's servers. That makes MMORPGs expensive to operate and sensitive to outages: a failing database or overloaded game server can affect everyone at once. Games usually split players into shards or realms to keep load manageable.
Example
When you pick up an item, your client sends the action to the server. The server checks the rules, updates your inventory in the database and tells nearby players what changed. Because the server is authoritative, a modified client cannot simply invent items.
Common misconceptions
- "Massively" means everyone is in one place. Most games cap the players visible in an area and use multiple instances.
- All MMORPGs charge a subscription. Business models include subscriptions, purchases with expansions, and free play with microtransactions.
- High FPS removes lag. Server load and distance still matter.
