RRIKER: Not sure if you still need this info, but I can confirm (unless I am victim to a glitch) that you *cannot* unlock "Patron of the Arts" without an Iron Man save, as there is no other way to get the 3-4 pieces of Concept Art without it (I have everything else but those, and no achievement).
"I will kill the machine, because it has to be done.
Get over what I have been, and then never need to run.
I will realize my dream with all the blood in my veins,
to fight the machine until none of it remains." ~mind.in.a.box
