The Stropp's World blog has an interesting editorial of the pros and cons for open sourcing MMOs
, especially those that have "died." Stropp examines both sides of the issue and makes some compelling arguments. "So, there are some good reasons for a company to open source the game that it is soon to retire, and there are a couple of good reasons against. What to do? If opening up the client is not an option, open up the server code. This would allow the open source community to take the software, install it on a community server and open it up to the fans. Other players might want to grab the source and create their own private servers, perhaps with different rule sets for PvP and the like. The life of the game could be extended for years, supporting a thriving community."
