Now, since I have the white Xbox without a hard drive, will DLC still work for me if I buy the add-on disc at the store? Or does it require NV and then the DLC to be installed to a hardrive like it would on PC? Also, which one should I get? I would like whichever one has the most new content. I am so bored of my guns, I want some new guns, and some new quests, and new armor.

DLC is XBL only... For now. So it's on your HDD. But get them all, good or bad, like or hate, they are part of the game.

Pick up a HDD of the Xbox at your local Game Stop or the like. Check on line as well.

Oh I see, I'll have to wait until they release some on disc then, I have HughesNet so xbox live isn't an option for me.
