I loved FO3 and you guys are making me want to pick up NV. I know it has to be dirt cheap at this point, was there ever like a GOTY edition with all the goodies in it? Or am I going to be chasing DLC?
Yes, it's called "Ultimate Edition", I picked it up for x360 about a year ago for $25 shipped (new). It has ALL the New Vegas DLCs, item packs, etc. Unfortunately, it's still plagued by bugs, that was the only real drawback to NV, you had to remember to save often because it crashed a lot and occasionally corrupts the auto-save.
As for that new site, it's unfortunate that it may be a hoax. From what I read about the morse code it implied it would involve "The Institute" (MIT in our world), which FO3 fans would remember Zimmer at Rivet City hunting for his runaway android.
Being a longtime fan of the series, I've been speculating for a while about where FO4 would take place, "The Institute" being one of those places, I also kind of thought Chicago as well, because of the Enclave presence in the ruined city.
Personally, I think it would be really cool to have a Fallout game set in my hometown (Huntsville, AL), mostly because of its history with the space race and the continued DoD presence. There are also several fallout shelters in government buildings around the city from the cold war still maintained to this day. Will it ever happen? 99% sure it won't, but I can dream right? I imagine it as a full game but similar to the Old World Blues DLC, but with lots of ghoulified pre-war scientists.
