This building thing will probably be the centerpiece of the DLC and it'll probably be based on improving skyrim and adding features like:


 * Adoption


 * Setting favorites for followers inventory (Like choosing them to wear a Steel Helmet over Daedric)


 * Training Followers to level up and learn new Skills (Such as Teaching J'zargo Master Destruction spells)


 * More Shouts


 * Quite a few Side Quests


 * Seasonal Foliage


 * More mobs: Fat Giants, Giant Mudcrabs, Goblins ETC


 * Spears, Mace on Chain, Elemental Arrows

and probably more.

Where most of this stuff is.
