T.J.: The Elder Scrolls V: Dawnguard
It's hard to put into words how big a Skyrim fan I am. Three of my favorite things in the world are Vikings, werewolves, and The Elder Scrolls series. Letting me play in the homeland of the Norse-flavored Nords and be a werewolf in an open-world Elder Scrolls game almost gave me a fanboy heart attack. However awesome you think Skyrim is, multiply that by Odin to get how awesome I think it is. The only thing missing was an organized faction of wussy-ass vampires (you heard me, consider the gauntlet thrown!) to tear apart with my Nordic werewolf claws. Dawnguard gives me that, plus a new werewolf-specific perk tree. It may just be an expansion, but with the relatively lackluster showing of PC RPGs at this year's E3, it was the one thing I was most excited to hear more about.
