I've beaten the main quest a while ago and I'm currently level 57. I have run out of stuff to do and I'm wondering if anyone has any suggestions. Thanks -$??m

Settlements. Make it your mission to turn every workshop location into either a large community that offers all services, or a smaller homestead/outpost for the people currently living there. Develop them all.

Max all your stats out, explore more maybe there is a something that you have missed to increase you power further, and lastly work on your settlements.

Thanks for the suggestion. Ill leave the thread here as a suggestion box for everyone to use. Thanks box, -$??m

Thanks I'll do just that -$??m signing off for the night

There's a ton to do even if you have beaten every quest available. Collect all bobbleheads, magazines. If you have the corrects saves you can go back to a point where you can side with another faction so you can try and get all the achievements. There is probably more, but that's all I can think of off the top of my head.
