They hold back on cross play, thank god. At the very least they are conservative with the competition, I don't want Live users on my PSN games. I'd assume most PSN players who PAY FOR THE SERVICE don't want the same. Cross play is a ridiculous attempt by MS to get a stake in their failing market share the same way they tried to mirror Sony's mic drop with sharing games at E3 with Backwards compatibility and failed. I pay for PSN, not Live. 

I'm not so sure, nothing to do with console wars. I'm far to old to be concerned with nonsense like that. I am however a tad frugal and want my money to go to the best possible service. PSN, is a closed system and holds has quality assurance, I wouldn't pay for it otherwise. I've played on live, I've played on steam and the only service that comes close to a private discord is PSN. And as I said before I don't want to have to pay to compete with K&M players or users with mods and hacks so freely available.

Oh can you make cross platform parties between ps4 and PC for fortnight? My kids play it on my laptop sometimes, or together on two ps4's. All 3 of us could play together if that is the case.

Btw kinda funny that the whole argument against enhancements for the pro consoles for multiplayer games are bad goes right out the window with cross play. Must be the same fps, draw distance, or unfair! Crossplay, you could be playing against someone with 144fps zero latency monitor, KB+mouse, 8K triple screen setup, contrast enhancement injection etc.

In my case it's reversed though, Fortnight stutters and lags a ton on my laptop. It's hard to aim for a landing spot, bit better on the ground, yet 15 to 20 fps is about it. My kids don't seem to mind. Must look for the settings sometime.
