Lots of good options, but I'll go with Minerva's Den from Bioshock 2. --- Note to GFAQs mods: You do an absolutely terrible job at modding trolling. Get better at it and give harsher punishments for it.
I remember I totally wanted to play that when I had morrowind on my Xbox but couldn't find and still don't know if there was a disc released version of blood moon for Xbox. I might try to find it now that I have morrowind on my pc :-)
Doesn't the game of the year edition have bloodmoon?
To answer the TC, I would have to say RDR Undead Nightmare...although anything by Rockstar seems to be amazing...Their DLC is like getting a brand new game. --- http://youtu.be/HR8Ia6vyV5Q She's an endless war, she's a hero for the lost cause,Like a hurricane in the heart of the devastation
BS2 Minervas Den is the best DLC I have played this gen. A fully contained SP game not some tack on missions that are basically cutting room floor junk probably well over half the length of the original game with story that is just as good if not better than BS2
