Completely hooked on this now. I’m level 24, at 25 I get the next level of gun nut perk that gives me access to more powerful gun mods. I wouldn’t get too carried away with the strength skill unless you build a melee character and want to carry shed-loads of stuff. Once you get a companion you can use them to carry stuff for you anyway, even dogmeat can carry stuff. I’ve based myself in Sanctuary, and I head back there regularly to store loot/junk in the workbenches, mod weapons and armor and cook stuff. Found some amazing weapons – Deliverer, Fusil Terrible, Reba 2, Kellogs pistol – used the latter to drop a legendary alpha deathclaw quite easily (with the help of a nuka quantum) I love this game 😀
EDIT : as others said, I never use power armour
