There are several existing virtual worlds running successfully. Some of them are Flash-based and some are not. We will introduce them here so that we can give them a try and get some inspiration before starting our virtual world design and development.

It is a kind of casual game virtual world where players explore in a small town and play multiplayer mini games with each other. It can be a good example of what Flash with socket server can do.

As one of the best-selling virtual world communities, it is worth taking a trial at this game. World of Warcraft (http://www.worldofwarcraft.com/), also referred as WoW, is a kind of serious game play virtual world that contains a huge worldview and complicated story.
