The only bad feels I have about Elite Dangerous are that if the developers ever shut down the server, I guess we're just done.
I really hate this trend with games these days. "Buy our game and all these cosmetic updates, and then when we shut it all down you're stuck with NOTHING."
Makes me wonder if you could pull off a huge, living universe that operated via periodic pushes and pulls to/from a central server. When the central server dies, you don't get any more updates to your local copy - the universe just sits, frozen in stasis until the end of time.
