Back in June, we talked about a fun little bit of trolling that Xbox and Nintendo teamed up for at the expense of Sony and its PlayStation 4. At issue was Sony's longstanding stance against inter-console play for multiplayer games that would otherwise allow for it, whereas Xbox and Nintendo players all over the world were happily playing MineCraft and Fortnite against one another. The end result of Sony's stance has been both a decent level of frustration by gamers that expect modernity in their console's features, and several YouTube videos and Twitter exchanges between Xbox and Nintendo highlighting that their own consoles had inter-console functionality. In that post, we said it was an open suggestion whether or not this public ribbing would change Sony's stance on the subject.

Narrator: it changed Sony's stance on the subject.
