Expected more for the buck
Dawnguard was more of Skyrim with one major exception: it wasn't fun. The vampire quests make the Dawnguard quest look like a circus of laughs, but the Vampire's quest turn out to be surprisingly bland as well. Much of what I wanted from the expansion made me look back to the previous expansions for the Elder Scrolls; Shivering Isles, Bloodmoon, and Tribunal. All offered something new and different, new expanses to explore complete with new cities and dungeons. Dawnguard was more dungeons including a new Dwemer ruin in case anyone was worried you were done fighting falmer. There is also a new area that is so dull and vacuous it makes Oblivion's gates feel like fun. This is not to say that the entire thing is devoid of content, there is plenty to be found if you go looking for it. There are a few cool story tidbits but if you are over level 50 and playing on a harder difficultly the Vampire Lord and Werewolf forms even fully maxed with perks are completely useless compared to leveled blades and spells. Coupled with Bethesda's legendarily glitchy products, boom, every once in a while you become a vampire lord falling through the abyss. Seriously the vampire quest line took me a little over 4 hours going slow, and my Xbox froze no less then 4 times during it. If you want to use the morphs, save often. This seriously felt in no way like an Elder Scrolls expansion, but more like a large mod made by closeted masochist Twilight fans.
