The term “lobby” refers to a system in which the actual gameplay activities do not take place in a world shared by all players, but in separate instances. These instances are self-contained pockets in the world, such as dungeons or battlefields. Players access these areas through a lobby. This serves as a type of activity browser. Here, players can choose which activity they wish to start. In modern games, “group gameplay content” often occurs in instances that can only be entered by a specific group of players. This is particularly pronounced in a “lobby MMO.”
