Don't forget the needless implementation of always-online single player games. Even for single/multiplayer games like PoE or anything Diablo, there's literally no technical need to have a connection. It's just fancy DRM for Blizzard and an excuse to milk you more microtransactions for PoE.

And before anyone regurgitates Blizzard's BS about anti-cheat, it's very possible to keep multiplayer characters on the server and single player on your computer and never have them interact or permit single player loot to be sold on their marketplace. Not to mention their regular online check for D2R. Blizzard has ALWAYS used aggressively hostile DRM. If they could virus bomb thieves' computers then they absolutely would.
