MMORPG Tycoon 2 is a single-player game about building the world’s greatest MMORPG - yours.
MMORPG Tycoon 2 is not an MMORPG; it is an entirely single-player game, played locally without any network connection to a server. It is a Tycoon game about running an MMORPG, in the same way that Roller Coaster Tycoon is a game about running a theme park. Build the world, set the rules, wield the banhammer, nerf the classes, and keep your subscribers coming back. All these and more are possible in MMORPG Tycoon 2.
Features
Build a huge MMORPG world, with well over 200 square kilometers of territory; that's nearly the size of the original release of World of Warcraft.
Buff and nerf character abilities at your whim.
Create towns, villages, dungeons, and monster zones.
Create and edit quests for your subscribers to complete (or let your designers do that for you!)
Extensive character creation options -- customize all of your player classes, monsters, and NPCs, their appearance, statistics, and attacks.
Get your subscribers addicted, then raise your prices, or start charging microtransactions!
