Too little, too late. Fortnite, H1Z1, CoD Blackout, and BF1 BR have all already made this game irrelevant. Bluehole spent too much time crying and trying to sue others over a genre they don’t even own, instead of developing and optimizing their game. Doesn’t help that they promised no MT’s during early access, and almost immediately went back on that and added pay to win MT’s. That’s why even with the XB1 playerbase added, they’ve been dropping in concurrent players. They’re currently at less than a million, from the over the 2 million they were once bragging about. Not releasing on PS4 at the same time as XB1 was a grave mistake.

PS4 didn't have early access back then either. Similar situation with ARK.

Ark had a 1 year timed exclusivity deal on XB1. That’s why it released as soon as that deal expired on December 6, 2016. Still as an early acces game. The final game came out on August 29, 2017 on all platforms. PUBG has a 1 year timed exclusivity deal on XB1 as well as revealed by Bluehole and PUBG Corporation.
 
There was and is a bunch of early access and in-development games on PS4:
7 Days To Die
Ark: Survival Evolved
Atom Universe
Darkest Dungeon
DayZ
Don’t Starve
Fortnite
Gwent: The Witcher Card Game
H1Z1: Battle Royale
Paragon
Realm Royale
Subnautica
The Tomorrow Children
Warface
Etc.
