Well first of all a game like Fallout 4 does not need huge advertising for years. It is not like we've been fed up with a new release every year, so that noone really bothers about it anymore. Another plus is that we only had to wait five months for release since announcement.
I have a problem with it technically still, and simply because of the gameplay we've seen so far that put so much emphasis on stuff that I largely do not care about (crafting and settlements), while other parts of that are essential to me were left out unknown for months and/or even until release. That especially is aimed at character development and quest design, basically the RPG elements. So much of this is still guesswork, though I tend to be more optimistic now than in June. Still I do not know essential stuff, like: Are there speechchecks (i.e. does Charisma replace the speech skill)? Are there perk or other attribute related checks? I always built my character around speech and sneaking so this is key for me, otherwise Charisma is not special at all. Also, do you have to chose between raising a stat and a perk, or do you have two to distribute. I guess you have to choose but I do not know for sure...Then some mechanics like the power armour are still hazy at best and while we have seen so much fighting and dismembered limbs (which I really do not care about) we have not seen much of the dialogue system and if it is as important as before or just a sidedish. I do not care for 11k lines of text if it does not mean anything in the world I am in, or if it is just a way to direct you to the next generic enemy that you can behead.
That being said, knowing Bethesda games, I appreciate that the game was largely done even in June, meaning that focus on bugs was priorized in the last months, which hopefully prevents the gamestoppers and broken saves that I encountered in every TES and Fallout game so far within the first 12 hours, and then again at hour 20, at which time I at least had a working save that was not right after character creation.
