Other players in FO76 are actually very nice. If your low level, high level people will just go up to you and give you things. PVP is optional and I never turned it on. You’re incentivised to join teams with many perks. You can just follow a team mate around and help them, and I’ve done that many times. Teams are temporary and small (max 4 players) so people are very open to you joining a team.
