Is Open Cobalt a virtual world?
No, not really. It is a virtual world browser and toolkit for creating your own virtual worlds. It may be helpful to think of Open Cobalt as a tool for accessing and interacting with virtual worlds that can exist locally on your computer or anywhere on a network – rather than as a virtual world in itself. This is not any different than how you might think of a web browser as a tool for accessing and interacting with web pages that can exist locally on your computer or anywhere on a network – rather than the web browser being a web page in itself. When you launch Open Cobalt for the first time, it loads a private home world by default. The Open Cobalt distribution also includes several very basic sample worlds.
