Man of Honour
All I wanted was FO coop
You might be able to get that in FO76 with pacifist mode. Obviously it's not finalised yet, but it looks like a possibility for maybe opting out of PvP and making FO76 a co-op multiplayer PvE game. I'm not sure about the details (for example, it's on up to L5 but can you keep it on afterwards?), and they're not finalised yet anyway, but it might be something for you to keep an eye on.
