First off:

I have played 674 hours of Fo4 according to Steam, so I would say that's pretty good assessment of the game.

No. That's more hours than the vast majority (like 99%+) of gamers will ever put into a single game. That is an absurd amount of hours for a game which you claim:

The replayability is low.

Also, to this comment:

TL;DR Felt like EA made this game, not Bethesda

You do realize New Vegas was developed by Obsidian, NOT Bethesda, which you didn't hesitate to praise within your very first "point:"

When I purchased this game I had fond memories of New Vegas and all the content to explore there. All the side stories, Big Mountain, Siere Madre, etc. The innumerable side quests within the game. New Vegas felt real. Like I had stumbled into a running working place, and I happened to take part in its story.

You hardly even mention Fallout 3 which WAS developed by Bethesda, just this silly comment which is basically still a complaint yet brushed aside:

In Fo3 the vault was at least fun.

I don't think you know fuck all about Fallout or Bethesda or you're simply baiting and doing a poor job at it.
