It's worth noting that this is a similar reception to Uncharted 4 (39 perfect scores to this game's 44 so far) and that, in my view, these are the sorts of experiences critics prefer. They want something cinematic, relatively streamlined and with a great narrative. Combat mechanics, depth of them, level design and so forth are kinda secondary to most critics, you can see it in how they review games. I remember reading about this phenom in regards to the game Mad Max which was loved by gamers but not critics, gamers really enjoyed all the stuff there was to do in the game... critics saw it as busy work. What we need to remember is to critics this is a JOB and the more hours required to give an informed opinion on a game the more annoyed they tend to become. As a Destiny fan I weep any time a review hits before the new raid drops, can you imagine reviewing a game whose best feature is absent?
Though this may seem like an effort to minimize the importance of how well this is doing, it's not really, if it remains at 96 then it's very high even for this sort of game. But when the disconnect between critics and fans occurs it's usually as it relates to games with a wider breadth of gameplay/depth, in fact, some of the more negative reviews for TLOU II will complain about the crafting, collecting or just how long and big it is. Only game critics will complain about length without implying there's anything actually worth cutting out, while the fans just want more. I think there's room in the medium for both types of games I describe, I consider TLOU one of my favorite games and put it right beside games I have hundreds more hours in, because some games aren't built for hundreds of hours. In the same sense that I've watched Back to the Future more than The Godfather but don't necessarily like it better. If you can get past the idea that them giving it a perfect 10 doesn't mean it's going to change the mind of a ND hater and is a 10 based on the idea of it excelling at what it's made to do (and let go of the fact that games that excel in the other way don't get the same level of recognition) you'll be doing okay. I still remember the people complaining RDR 2 wasn't completely different from 1 when it came out, like because it's getting such high scores it needs to transcend your biases against the sort of game it is, like if I as a non-fan of racing games played the new Forza and said "wow, overrated". Still, besides rare exceptions game critics mostly favor more compact, cinematic and often easy experiences, I've seen some commentary on this game's difficulty and I wonder if some of these critics are playing it on easy and still getting fucked up and that's the big difference here. I thought the first was a difficult survival game but never so difficult as to ruin the pacing/narrative with you beating your head against a wall on the same section over and over. I didn't play on easy, I rarely do.
This is a lot of assuming, though, from what I understand there's more openness to this game and there's a lot added to how the combat works. I just still don't see it as one of those 100+ hour games, but not every game needs to be.
