"Sony won't allow Fortnite players on PlayStation to play against their friends with other consoles – because those people are having inferior experiences.
The company might allow people to take part in cross-platform play on other titles, said the company's boss. But Fortnite on PlayStation will not get that privilege, he said.
And that's because the best experience is to play on PlayStation, he said. So allowing other people to play would be a compromis"
This is just sad. Sony should just say because it's because of the money.
