Types of Worlds

There are many types of worlds on the Internet. They can be very roughly divided into combat-oriented and social worlds. This division is a fuzzy one. Some people join combat-oriented worlds and then spend most of their time socializing. Some socially-oriented worlds have combat areas. It's like a big family. Sometimes you talk, and sometimes you fight.

The division between combat and social worlds is influenced by the software that was used to develop the world. (This is called the world server.) Here are some of the names that you may see associated with worlds:
