They'll probably see the voiced protagonist as a step forward in "immersion" for the player. Now you no longer just click text boxes, instead you get to hear what your character says! And it feels like you are having a conversation with NPC's.
Limited dialogue? It's also a step forward, because it makes the pace of dialogue faster as there are only a couple of words to choose from.
Romancing companions? In a progressive world we need to explore more than just violence in gaming and it is a good thing that Bethesda acknowledges this and allow for more variety in their gameplay. If anything will be criticized here it is that the super mutant can't be romanced.
The stat and perk system is more streamlined than ever and boy is that a good thing. All those darn numbers to keep a track of that made character development a chore is now replaced by a single point system that anyone in the family can easily use without feeling overwhelmed.
Fallout 4 for Game Of The Decade.
Even if we accept these viewpoints, I think the view that Fallout 4 is a terrible game is inescapable.
If we only compare Fallout 4 to Fallout 3 and make generous assumptions, its still a bad game.
Voiced protagonist and simplication (understatement of the century) of skills at least have some merit. While I, and most people here, think any benefit it outweighed by the harm caused, we can assume that these changes are neutral.
Graphics seem little better than FO3, especially after 7 years, but again we can assume that it is neutral.
The gameplay seems largely the same, and we can again assume that it is neutral compared to Fallout 3.
The main difference with Fallout 3 is the story, quests and world. From what I have seen, the quests are repetitive, the story is predictable and cliche, and the world is desolate with only one or two settlements.
Even if we are incredibly generous to FO4 and assume that many of the changes are neutral, or slight improvements, to FO3 (and ignoring the major improvements made in New Vegas), FO4 will still fall short in terms of story and world.
At the end of the day, its worst than FO3 in terms of its story and world, and that is saying something.
