I'm finally playing fallout 3 and I find myself burdened with junk. Lawnmower blades, vacuum cleaners, sensor modules, scrap metal, etc. Should I continue to carry all these? My brief survey of crafting blueprints seems to indicate that there is a distinct limit on how much you can do in the building department. Should I instead just sell everything that I get or is there a point in hoarding some of this stuff?
Will it ever be useful to fix my weapons? or are there other things I can do with them?
