I actually like it. For people who scream for a single player mode, the game basically plays like that now. The map is huge and your rarely stumble across others. Adds to the desolate weird feeling the world has. Also 90% of the people you run into are nice and friendly. People sharing ammo to low levels and not attacking as in pvp mode.
I wouldn't be opposed to a bump in player count though since I think the map is large enough to support it.
I think the current player count would be fine if the world was filled out with settlements, factions, ai companions, and a large number of settlement based and wandering npcs. But as it stands, the world is just filled with scorched, mole people, and super muntants that just stand there until you alert them.
While there's some non hostile wildlife in the game, the behaviors given to them and their rarity makes the game world feel dead in a bad way.
Like, West Virginia in fo76 is asthetically nice even if it's graphically dated. But the world feels lifeless and dead in that never changing, never reacting, "videogamey" way. And that needs to change somehow
