Just click on the link and get educated. Sony is lagging behind, imagine being an Xbox One original owner and being able to play next gen games. I use the cloud function on my Xbox Series X when I am trying out a game to see if I like it and then I will install it if I do.
I also use the cloud on my PC to continue my save on the gamepass games I am playing at the moment for example Forza Horizon 5 and Grand Theft Auto San Andreas DE. It's a wonderful feature and I feel sorry for owners of the basic PS4.
