I think people forget there are a lot more costs to keep a game running than just the servers or the people actively working on it. Even when something is in maintenance mode, there are groups outside of the game team doing work. As an example, if our back end systems change, then someone needs to go in and make changes to the game code to remain compatible with the back end systems. If that game doesn't have anyone working on it, then someone needs to stop what they're currently working on, and get back up to speed on how the other game's systems work, then make changes, then those all need to be tested, run through QA, etc, etc, etc. It becomes a cascading effect on costs vs return.
