To clarify, do you think the DLC will be something that will impress you and be exciting to jump into or will it be safer and more basic? I'm of the mind that the first DLC for Fallout 4 will be somewhat underwhelming, given what Fallout's DLCs have been like in the past. I am very excited to see what is coming for FO4 in 2016, but I know that when I think back to FO3, with the exception of Mothership Zeta, I found the DLC to be underwhelming. Now, in the case of Skyrim, Dawnguard was the first DLC to launch and it included one of my favorite NPCs of all time and had a questline that I thought was awesome, if not a little predictable. Granted, I know more about the lore of Elder Scrolls than I do Fallout, but I find that the ES DLC has stood out more to me than the FO DLC. I am anxious to see if I'm proven wrong, but I have this hunch that the next DLC is going to be kind of meh.
Now, if they would make a Bioschock-esque DLC that had us find or make a new aquatic based suit of power armor to explore an underwater lab/civilization and ultimately decide the fate of the place (that might be overrun with new mutated enemy types or what-have-you) then I would be very excited. VERY EXCITED. Hint, hint Bethesda
