Or as a responsible game developer studio you could release the server for your 15 year old MMORPG to the fan base. Turbine is working on releasing the server and the tools for creating new content to the fans now after they finally stopped the monthly updates last year.
From what I understand it has to do more with taxes then being responsible. Once the game actually shuts down you get a tax write off for some of the costs involved. If you keep the game running in any form. the tax write off is not available.
