Now now u 'no' that's a prohibited answer... Not every1 can afford a high end pc.
That's why some of us have a low-to-middling PC. Add a passable graphics card sometime down the road for under $100 and you've got a budget game machine that will run OB at decent but not "maximum" settings. Granted, it still costs more than the typical console, but probably less than double, and I can upgrade the main board and processor in another year or three for less than buying whatever new console replaces the current model. If you buy one of those pre-configured "name brand" PCs (Dell, HP, etc.), then you're pretty limited as to upgrades, because "standard" replacement boards, power supplies, and other major components won't fit the custom case.
Anyway, I'd much prefer a couple of options to a "fixed" hardcoe mode, or to no choices at all. Bethesda has done options before: "Best Attack" checkbox in MW, for instance.
