Aye, the one part of this that niggles at my gamer conscience is when I think about big publishers who invest our hearts in online games, and then tear it all down as soon as it benefits them to move on. Is it their right to do so? Yes. Does that make it awesome to do so? It's a gut punch to see an individual follow that example. Games like Wurm Online, Perpetuum, Mytheon, and Legends of Aria show that publishers can leave their work behind whilst they move on. While I can continue to play Odyssey, imagine if all of Tolkien's work had been deleted from store shelves the moment he was ready to move on from Middle Earth. It would not have been an improvement on our world, and the world will be dimmer without Odyssey's continued accessibility.
I would maybe argue that if one can't leave their creation in the world for its continued benefit, they haven't truly separated themselves from it, they've just found a different way to keep it. I'm not sure if that can genuinely be the same thing as moving on.
