The title pretty much says it all, but here I am to say a whole lot anyways. One thing we can look forward in this version of Dawnguard is that it should be far less buggy than the Xbox 360 version, which has been out for over a month. Since they have had more time to work on the PC release and it doesn't involve Kinect, it should be far less troublesome. Dawnguard hasn't received the best reviews, but it gives you a chance to jump back into a vampire filled Skyrim that gives you a decently long story to indulge in. You will have to choose between joining the vampires or joining the Dawnguard, who are basically vampire hunters, but from everything I hear it seems joining the vampires is a lot more enjoyable. So what is stopping you from jumping in to this new chunk of content? well, probably the hefty price of $20. If Dawnguard was awesome and unique as the Shivering Isles expansion for Oblivion then $20 would be no big deal, but it certainly isn't to the scale and quality of that expansion. Anyways, take a look at this gameplay from the first mission of Dawnguard.
