Well, I can see how making steel by leveling up attributes and perks is not feasible for a SP.
It takes 7 point in the Int category to get Forges, Chem stations and Work stations. EDIT: and Cement Mixers.
It takes an ADDITIONAL 16 points to get the crucible for steel... It feels a bit troll-ish to make people that want to build one on there own, spend so many points in such a weak category.
I would never do that. Spend 16 points for a small deal? Nope.
Spend the points on Lucky Looter and hope for the best? Oh Yes!
