From the PlanetPSX feature review:
"A lot of people have been on the fence about EA’s offered Battlefield 3: Premium package, dismissing it as that company’s version of the “Call of Duty Elite” package, but without the exhaustive online options for clans and so forth. But I think DICE had a different approach to Premium, looking to expand the action itself rather than the technical data behind it. They’re not concerned with how someone jumps into the action, just as long as they do it. Their first DLC for Battlefield, Back To Karkand, wasn’t half bad, though there really wasn’t enough in this pack to separate what you were doing in the main game. It was good, though, especially for fans."
