I actually think its a crime to trade.in skyrim or something. I would advise you not to. I'll go hardcore on Skyrim whenever ps3 gets the dlc. Havent even done any DB quests in my current playthrough though.
Prob should go back and play borderlands. Completed the game but not all the dlc.
Shit beat me to posting it Soupman. Hearthfire looks nice. It obviously isn't a huge DLC like Dawngaurd but awesome none the less. This certainly won't be the last from Bethesda for Skyrim. I expect at least one more huge questline/expansion and some more of these smaller add ons.
