Fallout 4's first big DLC will definitely be big.
Far Harbor, the upcoming DLC for Fallout 4 will add a decent chunk of content to the game. Though details are scarce this far out from release, Bethesda's VP of marketing and PR Pete Hines revealed one interesting fact about it.
Hines was asked on Twitter whether or not he's able to talk about the size of Far Harbour. Hines replied, confirming that it will be bigger than Shivering Isles, the big expansion for The Elder Scrolls 4: Oblivion.
@SirCabbage it's bigger in size than Shivering Isles. I asked.
