My opinion on Fallout 4
Fallout 4 takes what Fallout New Vegas did with companions and advances it, allowing you to judge what a companion likes and dislikes by way of the "companion liked this" message that can pop up
Fallout 4 took the idea of weapon customization, which FNV pioneered, and improved it, allowing you to mod your weapon as you like and either buy or build said mods. Fallout 4 also has better graphics and has more vibrant colours, which fits the theme that this game pioneers, that theme being that hope exists in the wasteland, no matter the desolateness of the land, that people can hope to rebuild in a new land, one that, while ravaged by war and american pre-war capitalist values, has plenty to help humanity renew themselves. The previous fallout games each had different themes, fallout 1's theme being that anyone can make their mark on the land, anyone can be a hero. Fallout 2's theme was that everyone has a destiny to follow, they just have to look inside themselves to find it, and that purity is not a virtuous ideal to behold as a destiny. Fallout 3's theme was that the world has became hell, and people must go against the grain to help each other, Fallout NV's theme being that those who are stuck in the past will lead to the future's endangerment.
One of my personal things i love about fallout 4 is that, despite people complaining about lore breaks, Bethesda actually didnt break any lore besides Jet's origin. What Bethesda did was what is called addition retro-continuity, they added to the lore through a retcon. Fallout 1 and 2 did not talk much about Pre-war power armor and the APA's origin. Fallout 4 states that the X-01 inspired the APA that the Enclave use in Fallout 2. That loadscreen, the one that created the entire argument over X-01's post war or pre war origins, is MISREAD. It doesnt state that X-01 is APA, it says that APA was a design that was used over the older X-01 SERIES models. I use caps to show emphasis, Bethesda added to power armor lore by making each power armor part of a series. Therefore, T-45D is canon, but part of the T-45 Series of powered armor.
And before anyone complains that,"power armor wasnt ever powered in the games", that's a gameplay mechanic that actually fits lore. In Fallout 2, it's stated that the T-51 power armors used a built-in Microfusion Pack, one that would need a start-up, I.E the Fusion Core. In fact, T-45D's had used small energy cells (Microfusion Cells, the ammo for laser rifles) to fuel it's power systems but that the later powerarmors in the T-45 Series had done away with this, preferring the T-51B's power source.
APA is implied to use a micro nuclear reactor as well, as shown by the glowing fan, which X-01 DOESNT HAVE.
Another thing i like is that they did make the BoS as people saw them in Fallout 3. Yes, while it seems like the BoS in Fallout 4 are simply nazis, that's not so. In reality, no one seems to realize that the BoS still actively recruits wastelanders, as proctor Ingram says so if you ask her what she was expecting after she states that you (the player char) werent what she expected. She tells you that she expected a wastelander as the last batch of recruits they picked up were "wastelanders, dirty and beaten-up, looking for a handout". Last has multiple meanings in this case, she either could mean that they were the last batch, as in they werent recruiting anymore, or that they were the last, as in they are recruiting but they were the most recent batch before your recruitment.
Yes the BoS seems to have a Nazi stance against Synths and mutants, but that's easily explainable. The BoS hate mutants because they see mutants as an example of the US pre-war govt's failure to be smart with their tech, The BoS was created in part due to the hatred Roger Maxson held for the scientists in Mariposa who were part of the government project there, which was to test the FEV on P.O.W's and fellow soldiers. On synths and their hatred, the BoS hasnt actually seen a 3rd gen synth, they've only fought the frist 2 generations, who are merely robots bent on fighting under the direction of the Institute. They dont see a 3rd gen until The quest, "blind betrayal" where it is revealed that Danse, a BoS paladin and a available companion is revealed to be a synth, this is the BoS's technical first encounter with an third-gen synth. In this quest, Arthur can be talked down, and convinced that Danse should not be killed, this shows that Maxson is willing to compromise despite what he's seen, and what he's seen is flawed as he's only seen the first two generations of synths who are just robots.
Synths and the third gen have even sadder stories if you read their creator, Alan Binet's terminal in his quarters in the Institute. You can learn that that Eve, his "personal synth", can dream, and robots can not dream. This is a good reference to Blade Runner and the book that inspired that film, "Do Androids dream of Electric Sheep" by Philip K. ♥♥♥♥. Synths cant dream, because Synth means robot, but you can also learn from Father's terminal entries that he forced the institute to call their Androids "Synths" because he didnt want them to be acknowledged as beings with free will and rights. And furter more, if you go to the synth retention bureau and talk to Doctor Ayo, he mentions what the SRB does, they mind-wipe synths after Retention, as to make them compliant. This shows that the Institute fully knows that if a thrid gen could, it'd free itself, so they capture them and wipe any idea that the synth could be free. And it's even sadder when you persue the Railroad questline. In one of the quests, you go and find alan binet's son, who turns out to be Patriot, the railroad mole within the institute, and he reveals that he's working with a synth to free 13 synths, this synth tells you that the third-gens have will but pretend not to as to keep them from being mind-wiped, and that some synths have acted as if they had no free will for so long, that it becomes true, they physically lose their minds and become compliant. Coursers are another example that the synths have free-will. A courser is emotionless, emotions make humans act to save themselves and others, if a killing machine working under a faction that strips the rights of their standing army had emotions, the Institute would be in dire straits. Third-generation Synths arent robots, they are human clones, if you watch the machine that builds the synths build, you can see that they build a third gen cell by cell.
People that complain that "fallout 4 had no bad guy", yes it might not have, but Bethesda really tried to push the idea that the Institute is a bad faction into your heads.

Do i recommend this game?

Fully, if i could endorse it and get money off of endorsing this game, i would jump at it first chance.
Fallout 4 is a game that has a story that is hidden in every terminal, every note, every person's story, while the main plot of the game might not be well-written, the game does good by fallout standards by making every location have a story that pushes the themes of fallout, be it the story of Vault-tec and their sleazy experiments on unsuspecting people with the permission of the government, or the story of a faction that forces it's own creation, to live in constant fear that their ability to think for themselves will be stripped should they display this ability openly.
