..The Elder Scrolls V: Skyrim..

(Continuation)

The sound design in Dragonborn is top notch too. The music is a combination of remastered favorites from Morrowind and a number of new tracks, and the only complaint I've found with the voice acting so far is the voices of some of the nords you encounter: their accents, for some reason, sound a bit off. 

As far as game mechanics are concerned, you can look forward to a whole host of new shouts, new armor, and weapons, a new house with enough storage space to put most of your old Skyrim houses to shame, and a whole host of new (or old, depending how you look at it) foes to do battle against.  Oh, and you can ride a dragon - though don't get too excited; you don't actually have direct control over the beast.

The story in Dragonborn, too, is oddly intriguing. I found myself genuinely interested in how things would pan out against Miraak, and the whole expansion, particularly in the later stages, had a delightfully Lovecraftian vibe to it, with all the forbidden knowledge and eldritch abominations floating about. It was a nice change of pace from the main game's focus on war and dragon-hunting.

So, long story short... if you were ever a fan of Morrowind, and you only buy one piece of Skyrim DLC this year... it should be Dragonborn.
