ah, I'm on PC so i assumed it was the case across the board
...why though? how could it possibly be advantageous to let PC players tool on your players lol
It's just blatantly done to try to hurt Xbox/Switch really.
They are apparently less concerned with PC gaming; maybe because they publish to PC? They also do sell some laptops and whatnot I think.
And yeah if I want to crossplay with people I'll just jump on my laptop anyway.
Really the only annoying thing is I'd like to play Fortnite on Switch; and I'ma lose my fancy pajamas and my umbrella and custom hammer or whatever! WAHHHHHHH!
Sony don't see a PC as a direct competitor for the Playstation, that's the reason why they don't care for cross-play Steam/PS.
Also, what exactly is there to hurt ? The Switch momentum is already fading away for three months straight now and will probably die by itself in 2019 when the PS5 and the new Xbox will be announced at the end of the year. The Xbox is currently dead and the Playstation brand is even a bigger monster than the PS2 days when it comes to sales (and profits !).
It's just them being dick because they can afford it right now and because it's in the company DNA. They won't stop, it's like asking Nintendo to stop milking their dumb fanbase.
