i enjoy the game. The map is big enough that I've spent a few hours and barely gone anywhere due to all the locations in a small area. I like the holotapes, the voice acting seems good. The enemy variations are cool. There are things I wish could be better, like the shooting being more fluid (not Destiny level but ya know) but Fallout 4 made shooting a lot better compared to Fallout 3/NV.
I've played on a launch day PS4 and now a PS4 Pro, they run pretty much the same.
It doesn't run flawlessly, but does any game not have bugs? Witcher 3 crashed a lot for me, the new Spiderman has crashed a handfull of times.
Sometimes I play Fallout 76 with my fiance, sometimes I don't. I haven't had any griefers trying to kill me and actually haven't done any PvP.
