Wikipedia: "In massively multiplayer online games, an instance is a special area, typically a dungeon, that generates a new copy of the location for each group, or for certain number of players, that enters the area. Instancing, the general term for the use of this technique, addresses several problems encountered by players in the shared spaces of virtual worlds." -> wikipedia:Instance_dungeon
