This E3 has been a good one for many who are fans of playing online games with friends and strangers across different console and PC platforms. Psyonix announced that a newly announced Switch version of Rocket League would be able to interact with existing versions on the Xbox One and PC. And Microsoft announced that online Minecraft players would soon be united across Switch, Xbox One, PC, mobile, and VR platforms.
Missing from both of those lists is Sony's PlayStation 4, which will keep its players segregated to the PlayStation Network for the time being.
“The honest answer is PlayStation has not yet granted us permission," Psyonix VP of Publishing Jeremy Dunham told Polygon regarding the reason for the Rocket League's cross-platform block on PS4. Since Psyonix runs its own servers and since those servers have already been certified for Microsoft's strict technical and security requirements for tying in to Xbox Live, adding PS4 is "literally something we could do with a push of a button, metaphorically," he added. "In reality it’s a webpage with a checkbox on it. All we have to do is check that box and it would be up and running in less than an hour all over the world. That’s all we need to do.”
