Engagement? Sony have the higher market share. They have the marketing deals for franchises that XB used to have. They have exclusive content only on PS, like Spiderman in Marvel Avengers, or Joker levels in Batman Arkham. Sony put a picture of the PS5 logo on social media and got the highest liked gaming related post in history. Then they topped that with the controller pic like a month later. "Engagement", pffft!Yes things are not in a bubble. It's about engagement. I'm sure there are Xbox owners that convinced a Playstation owner to buy a game so they could play together. That game purchase and possible DLC wouldn't have happened if crossplay wasn't a thing. It's such a shortsighted view to think Sony (and their users) don't benefit from this.
I'm not seeing it. PR wise Sony should get a small boost and a pat on the back for doing it. But as we've seen, they still getting dogged for not doing it sooner, or for wanting a something positive from it via the royalty fee.
But business wise? It still makes no sense. The gaming media are all like "C'mon Mr Sony Hare, let the little old XB tortoise catch you up, it's not fare, it's anti consumer of you even".
Meanwhile MS aren't "playing fair", backing the money truck up to Bethesda and spunking out 7.2B. But no one seems to call them on that, because everyone wants game pass for cheap.
If you start down the slippery slope of removing reasons for people to want your new box, eventually you're fucked and you lose the ability to effectively market your console the next time.
