Diablo 3 comes to mind as the canonical example of this, but it&#x27;s a PC&#x2F;console game rather than mobile. Single player mode is still run by a remote server, and if you have a bad internet connection or they have a server outage (which has happened many times) it will be unplayable.<p>Blizzard has been much better than most companies about keeping its online infrastructure up and running long after a game loses popularity, but even they won&#x27;t be around forever.<p>On the mobile side I don&#x27;t think that&#x27;s a common strategy (Candy Crush and Angry Birds aren&#x27;t going to stop working), but the purely multiplayer games like Ingress and Clash of Clans will certainly shut down someday.
