I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I read this ages ago, but I recall it touching on owners of virtual pets forming groups to try to keep their pets and the environments they live in going after the company that originally created them all folds. Well, I just came across a real-life example of something similar, although from the sounds of things there won't be a happy ending. Details under a spoiler tag, because it's depressing:(show spoiler)
Another thing to add to the "reasons why DRM sucks" list.
