The biggest piece of news for Minecraft at E3 this year is that it’s going cross-play with most platforms. Minecraft players on the PC, Xbox One and Nintendo Switch can play with each other.

Rocket League was announced for the Nintendo Switch. Guess what? Owners of that game on the PC, Xbox One and Nintendo Switch can play with each other.

PlayStation owners are out of luck. Eurogamer approached PlayStation global sales and marketing head Jim Ryan specifically about this. He wasn’t 100% clear on the reason for their choice, but he does suggest it comes down to stakeholders and commercial viability. Here’s the exchange.

Minecraft works cross-platform between Switch, Xbox and PC. Today, Rocket League was announced as working cross-platform between Switch, Xbox and PC. Both don’t work cross-platform with PlayStation. Now, is this Sony not playing ball? What is actually going on here?

Jim Ryan: It’s certainly not a profound philosophical stance we have against this. We’ve done it in the past. We’re always open to conversations with any developer or publisher who wants to talk about it. Unfortunately it’s a commercial discussion between ourselves and other stakeholders, and I’m not going to get into the detail of that on this particular instance. And I can see your eyes rolling.

Well, you must see that PlayStation owners are upset. They want to play with Switch owners, PC owners and Xbox One owners for these two big and important games, and they don’t have an explanation why. That’s what I’m getting at, really.

Jim Ryan: Yeah. We’ve got to be mindful of our responsibility to our install base. Minecraft – the demographic playing that, you know as well as I do, it’s all ages but it’s also very young. We have a contract with the people who go online with us, that we look after them and they are within the PlayStation curated universe. Exposing what in many cases are children to external influences we have no ability to manage or look after, it’s something we have to think about very carefully.

I didn’t think Nintendo would be open while Sony remained shut, but here we are…
