Mirandus

Mirandus is a massive multiplayer online role play game (MMORPG), where everything is owned by players. Players can own deeds (There are 1625 in total) and place those at any open spot. Then they can place their buildings there, such as taverns, forges, farms and even castles. These will replace what NPC’s normally do in an MMORPG. So when an adventurer has to rest after fighting a dragon, they now go to a player owned tavern and pay the player that owns it to rent a room, instead of an NPC.

The world is literally run by the players.
