An "instance" is a term used in online role-playing games to describe a means of creating a private space for a single or small group of players. While a majority of persistent world role-playing games offer large-scale areas with simultaneous activity for the population of a particular server or realm, settings such as dungeons are typically "instanced" locations that provide a more personal experience for a small party, larger raid, or solo adventure. The chief benefit of using instanced areas is that players do not have to wait for or compete with other groups to complete quests, slay creatures, and so forth. Examples of online games featuring instanced areas include Guild Wars, City of Heroes, World of WarCraft, and Lord of the Rings Online.
