Uhh no...
Unfortunately imho this is not the case, at least in my experience so far. I haven't see the wit nor the style of the first Fallout games captured within FNV, as was the case with Fallout 3. The same issues still pop up - for example the game still tells you that you need exactly NN% to pass a skill check, totally destroying any immersion one may have. My pet hate, the AI, is still as terrible as usual. The perks are still somewhat uninspired.
On the other hand, I don't believe that Fallout 3 was utter crap, just not as good as it could have been.
75% is about right in my book. :)
