They both tend to be the same price, and from what I surmise, the Limited box provides access to China Rising IF you preordered it (the box art doesn’t make mention of preorder, but the specifications pages on the retailers do).
There is no gold stripe on the top of the cover art regarding the DLC on the regular version.
BUT other retailers are selling the Limited Edition (via product description) with no mention of providing any additional DLC.
Soooo, if I were to buy a Limited Edition at this point, what should or shouldn’t I be expecting?
Walmart is ambiguous to whether you needed to have to preordered to get China Rising (includes gold stripe).
Best Buy reads a bit more terse/formal and seems that you must preorder to get the China Rising (no gold stripe on box).
Tiger Direct makes mention of Limited edition, but no gold stripe on the box, nor is there anything in the description about DLC.
How does buying Limited impact my ability to get Premium down the road (if at all)?
