Ehhhh. It's definitely becoming a thing that even a historically single player series is expected to have online features.
For some, yeah. But then you have Assassin's Creed, which added online co-op (the only compelling thing the franchise tried in years, and the reason I planned to buy it until it released as a buggy disaster), then ripped it apart to give us two players to choose from (because so many companies gotta make sure a female protagonist exists). The Witcher 3 didn't do it. Dying Light did it, but didn't force it on anyone.
Really, the forcing of online is much greater for patching than anything. So many games launch without being finished that you have to have online to play it out of the box. I mean, "going gold" now seems to mean the game is ready for its first major patch.
