Who defined playable? Take Diablo 3 and 4. They are shared world games, are they playable without them? Maybe to you’d but to me they’re not. world of Warcraft has a rich questing experience which doesn’t require playing with other people - is it ok if they just switch off multiplayer content? That’s a different game, IMO.
