Casual game design versus MMOG

Games in virtual worlds can be divided into two types — casual games or massive multiplayer online games. In virtual worlds with casual games, there are many types of mini multiplayer games that players can join from the lobby. Every mini game takes minutes to play with several competitors together. Players may continue to play different types of mini games after each round ends.

In contrast to casual game types, virtual worlds with massive multiplayer game design requires players to play in the same world. It is much like traditional role playing games in which players keep finishing quests in the world to make the story progress.

There can also be a mix between them. Some virtual worlds provide a bunch of light-weight mini games that players can play with each other for fun while at the same time, helping players to keep finishing quests and exploring the world.
