As someone who has played a bit of FO3 and Skyrim and was interested in FO4, but didn't follow the hype or launch. I have no clue what most here are talking about. It's pretty much what I expected visually and I'm maxing it on a 980Ti. Storywise it's in line with what I expected, pretty typical RPG gaming stuff. The environment has a few surprises and the combat is definitely more polished than before, but can be difficult without the right weapon. You're probably going to use quickload often. UI is still a bit of a mess.
If you didn't follow the hype and a Skyrim in post apocalyptic setting with nicer graphics sounds interesting then you'll probably like it.
