So they going same route as Xbox......
It's the AAA games that sways the perception and brand recognition. The proof is in the sales. As long as Sony delivers on those kind of games, they will remain on top. This is, of course, looking at it from the business point of view. Playstation business as a whole will do damn well fine and even exceed expectations for as long as they continue to give and deliver games that are GOTY material. They said they are doubling down on AAA games. We'll see.
Now, let's remove the business side of the equation. You might be one of those who love the AA creative games. My question to you is this, what difference does it make to you if the makers of next AA creative game is not on Sony's payroll?
Do you fear that these games will not be made anymore? It doesn't follow that because Sony will stop making these AA games internally that such games will now be ignored by developers or even Sony. As long as Sony is willing to foot the bill, those games will be made.
What difference does it make, from Sony's perspective, to hire a 3rd party studio to make these beloved AA creative games?
Answer: It will be cheaper. The rights to buy them or the rights to put them in a subscription service (as I suggested in my first post) is a lot cheaper since those games will release on all platforms, the risk is less and the reach is wider.
What difference does it make to you?
Answer: Nothing.
