We have repeatedly talked about cross-play e Sony, the only company that still "beats" against the possibility of being able to play certain multiplayer titles with players in possession of other consoles.
One of these games is the famous Fortnite, which he gave starting point for discussion to the CEO Kenichiro Yoshida about the reasons why the Japanese company does not want to open up to cross-play: simply Fortnite, on consoles, must be played on the PlayStation 4:
Regarding the cross-platform, according to our point of view, PlayStation is the best gaming console. We believe that Fortnite on PlayStation 4 offers the best user experience.
According to Sony, therefore, there is no reason to give PlayStation players the chance to play against users of other consoles, since that of Sony is the best to have fun with the title of Epic Games.
