For a long time, Sony stood as a bastion against anything to do with cross-console cross-play. However, the success of the feature has apparently changed some opinions.
Early on, when the topic of cross-play between PlayStation and Xbox (and of course PC) arose, Sony defended itself with hands and feet against the topic and largely closed itself off against any attempt to allow the feature. It wasn’t until 2018 that Sony reluctantly allowed the first titles with this feature, and only with resistance (or when funds were poured, see Epic vs Apple). Cross-play on PlayStation was not deactivated until May 2021, although the background is unclear.
Basically, Sony now seems to be bowing to the success of the feature and the fans’ desire for it. In an interview with Axios, Sony CEO Jim Ryan said that they support cross-play and encourage its implementation after the great success of the feature in games such as Fortnite, Call of Duty, Rocket League or Minecraft. The number of such titles will continue to increase as more and more games make the leap from closed ecosystems to cross-platform solutions.
Seems like Sony has finally made it into the game scene in this regard. For us gamblers: inside can only be good.
