The Medusa Engine is a C++ based MMOG engine. This engine was used to develop "DarkSpace" a space based MMORTS released in 2001.
Been working on and with this project for a few years. It is because of this game that I took an interest in becoming a professional game developer. A real treat to have an engine of this quality and size be free and open.
I have been working with this project for a number of years. Although I am not a professional developer, this has given me a great opportunity to learn about game development and just how complex it can be.
