Monetary concerns are preventing Sony from allowing cross-platform play between the PlayStation 4 and other consoles.
The company attracted renewed criticism on that front this week after it was revealed that Minecraft will soon allow gamers on Nintendo Switch, Xbox One, PC, mobile and VR to all play together, and that Rocket League players on Switch, Xbox One, and Steam will soon be able to do the same.
Developers of both games petitioned Sony to join the party, but to no avail.
Whenever cross-platform play has come up in the past, Microsoft has insisted that the ball was in Sony's court, and it appears that is true: Speaking with Eurogamer, PlayStation global sales and marketing head Jim Ryan said Sony's reasoning for holding out was about money.
"It's certainly not a profound philosophical stance we have against this," said Ryan.
"We've done it in the past… 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.
"We've got to be mindful of our responsibility to our install base," he continued
"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."
When Eurogamer's Wesley Yin-Poole pointed out that extremely family-friendly company Nintendo had signed on for cross-platform play, Ryan simply replied that Sony wasn't in currently talks to allow the feature.
In barely-related news, Sony announced overnight that it has sold 60.40 million PS4s to date.
