Sure, you can come back, but who wants to do that?
You’ll pout and moan every time you have to drop that Iron Sword because it puts you over the top, or every time you encounter that huge stash of Steel Armor at the end of a dungeon when you’re already at carrying capacity. In The Elder Scrolls V: Skyrim for the PC, PS3, and Xbox 360, if you’re anything like me (a loot horder) then you’ll be pretty frustrated early in the game that you can’t carry very much weight in order to get all of the loot out of a dungeon that you conquer.
