I started to play Fallout NV because I was told it is a very good game. I loved it and I was afraid how Bethesda will deal with that in their Fallout 4, because I had the feeling nothing can be done better.
But I have to say after 1/3 of the game, that their decision to make it different is a good one. Because even if there are not similar stories like in Fallout NV, I don't miss them and I'm not bored. I really can enjoy this game.
I'm sorry, but I cannot see what it should makes it looks like Skyrim - except it is their style of building world. What makes you think it is like Skyrim?
I know about other games that it could be compared to - like Farcry of Dragon Age Inquisition (sorry about that) where you can find similar mechanics and it is combined with mods that was made by fans for Fallout NV - again - where did you get Skyrim? A lot of features are taken from the most successful mods. So actually it seems like Bethesda did favor to their fan base? Fallout franchise was never like Call of Duty - so why do you say that players will buy that rather? I was told it was always meant to be post-apocalyptic RPG even in f1,2.
And about those new features: it has inner logic - it is something what you could do if you would have your family and a kid before and just left vault.
But if it would be just that, I wouldn't like the game. But the whole world, how it is build is incredible cool, fascinating and interesting. All the critics seem missing that point... Also if they say the story is shallow - the whole Fallout world is telling a story, is evolving and growing with you. From all those games that tried to do the same, I think Fallout made it really interesting for me.
The only problem I can see is if you don't like building, family, etc. And you expected that sarcastic, not really serious tone of Fallout NV. So you can say you miss that. but still it is well made in what it was intended.
And a lot of players criticise the companies with franchises that they just copy past something. This game is about different approach to Fallout world, they tried something new, But still for a lot of players it is a reason for hate. What was wrong again was support for keyboards.
I don't really want to defend the game - but I just wish the reviews would be more fair.
