Man, based on the LFG feature on Xbox One, the game is already dead and has the same low numbers of people searching for a group as in the deluxe week, so the low numbers weren't just a deluxe early access thing.
As comparison, right now,
People searching for a group, worldwide:
Battlefield V: 50
Fortnite: 1700
Fallout 76: 200
Forza Horizon 4: 60
Black Ops 4: 430
PUBG: 100
RDR2, which doesn't even have a Multiplayer right now: 60
I just can't find people to play with which is crazy since it's a freaking pvp multiplayer game and even worse, one of the biggest, Battlefield! Crazy.
