Existing virtual world games
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.
Club Penguin

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.

World of Warcraft
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.
Club Penguin, Mole, and Dofus are Flash virtual worlds but World of Warcraft is not. It is developed in LUA, a scripting language, and C++. WoW is a very huge 3D virtual world that contains over 7000 quests and 40,000 non-player characters. The 3D environment with large graphic assets exceeds the limit that Flash player can handle. According to a document from Blizzard, the company behind WoW, in 2009, the World of Warcraft ran on over 13,000 server instances.
