I finally got back into Skyrim, now that I got to borrow it from a friend. Just captured Odahviing, so I'm almost done. After that, I need to get a PSN card, beat Borderlands and it's DLC, then get Borderlands 2 and whatever DLC it has by then.
As far as Borderlands DLC goes, I suggest you skip Mad Moxxi's Underdome Riot unless you are playing with friends. It's basically just arena-style fighting of wave after wave of progressively harder enemies, and it's very obviously balanced for a team of players to take on.
