There's no way any of the reviewers giving this game a 10/10, or even a 9/10, played through to the ending.
**Spoilers Below**
To note, I sided with the "Brotherhood."
I just finished and the ending is offensively bad. They somehow managed to make it worse than Fallout 3's ending. My character didn't even mention the fucking faction he'd aligned with in the 30-second cutscene that is supposed to show... growth? Character development?
Man this game was clearly dropped on its head sometime during development, because it can't remember if it wants to be an RPG that lets you decide who your character is and what they stand for, or if it wants to tell the story of a guy who lost everything and was shunted into the unforgiving world of Fallout. It does neither one well in the slightest, and as a result has neither character nor story to speak of.
I am honestly baffled by how this game made it past QA or past play-testers. Glaring design flaws are integrated into the foundations of the game, from voice-acted protagonist with a pre-defined story but not a pre-defined character, to the removal of the skill system for a perk system that manages to be blander than wheat bread, but lets also not forget the baffling removal of the faction reputation system for like/hate relationships with companions shallower then a puddle, or the complete retread of Fallout 3's final mission, except without any of the atmosphere or excitement!
At least when you were following Liberty Prime around, bored out of your skull as he kills the Enclave for you (when his pathfinding decided to work) there was a war going on and it felt kinda cool. Here, eh, the fixed the pathfinding I guess? I just followed him around in broad daylight while he killed some synths. Apparently The Institute's defenses boil down to "teleport in 4 basic synths at a time carrying basic institute rifles." Guess they didn't want to survive very much. You honestly do not have to fire off a single shot through the entire final mission.
So you meet Shaun again at the end of things, and you get to say exactly 4 things to him, so choose wisely! There's no tension here, no drama as a father and son, forced to fight because of the son's complete moronic, almost cartoonish, evilness meet at the end of things. You can't try and convince Shaun that you're side is maybe right, you can't get Shaun to step down and surrender, you can only get the codes to shut some Synths down, a completely unnecessary act as, like I said, it is unnecessary to fire off a single bullet what with your entourage of power-armor wearing, mini-gun wielding brotherhood knights.
Then, in the final death-knell of Bethesda's character assassination of The Brotherhood of Steel, the Brotherhood blow the institute up! Yeah, that's right, The Brotherhood of Steel, dedicated to recovering and utilizing lost technology, just blow up the most advanced facility remaining on the face of the planet, because robots are evil grr we gotta nuke 'em. Can you talk The Brotherhood out of this action? No. Can you even bring up the fact that maybe, just fucking maybe, it would be possible to take control of and utilize synths and synth making technology for the greater good, like The Brotherhood was founded to do? Naah, that would be smart, and Bethesda doesn't do smart dialogue.
This is what I mean when I say that the ending is Offensively bad. I mean I could go on for fucking ever about the insane design choices in the game, but what really pisses me off is just how utterly shit the writing is, because, and I ask this as an honest question, why is the writing so atrocious? Can Bethesda not hire good writers? Did all the good writers in the world just form an iron-bound pact with each other to turn down job offers from Bethesda?
No, the writing is shit because Bethesda knows they don't have to try, people will buy their game and reviewers will rate it high anyways. That is why the ending is offensive, because Bethesda could have tried, they could have worked hard to make a better game with an ending that had some small amount of relation to that game, but instead they spent five minutes doing what can't have been more than one-take of the main character spouting baffling nonsense about home and family and rebuilding. My jaw dropped from how bad the ending was, I'm still shaking with disbelief as I write this, because I just do not understand how nobody at Bethesda watched this ending and proceeded to smack the person who wrote it upside the head, fire their incompetent ass, and spend the ten bucks to get a five year old to come up with a better one, because, and I am being completely serious here, a five year old could write a better ending.
I mean, I do know how nobody at Bethesda said anything, and that is because they simply didn't care.
Then, to top it off, the game offers a small glimmer of hope as the leader of The Brotherhood tells me "It's not over yet!" I think, "Hey, maybe there's more, maybe there's unique post-game for each faction!" Only to be informed that, while the main quest was over, I needn't worry, as The Brotherhood had an infinite amount of radiant quests left for me to tackle! Also here's a jetpack, now fuck off.
A still photo of a middle-finger would have been a better ending to this game, because at least it would have been honest. Really a big middle-finger would work well for the opening too, it would set the stage for the game.
As a Fallout game I cannot rate Fallout 4 anything but 0/10, complete critical failure of comprehending or implementing a single one of Fallout's central themes.
Story: 3/10. Despite my long rant there are a few moments that honestly captivated me. These moments are inevitably followed by let down as soon as I have to speak with someone again, as the dialogue system ruins any chance of an engaging conversation with any NPC, even if the dialogue wasn't written by someone who I cannot say for sure understands the basics of communication between human beings.
Combat: 5/10. The only thing that one might be able to say is noticeably improved from previous Fallout games. Even then it's not up to par with any action RPG you'd care to name. Melee and unarmed combat is the surest way to get yourself killed, stealth is OP as all fuck, and with the new perk system the way you play the game never really changes or upgrades, you just do more damage while doing the exact same things as before. Still, it is competent, and I had some amount of fun whenever the game had the balls to actually be difficult and require strategy, which is absurdly rare.
RPG mechanics: Fallout 4 is not an RPG. The Perk system, the last vestige of being an RPG, is boring beyond belief. Gone are perks like "Terrifying Presence" or "Confirmed Bachelor" that can really change the way you approach the game. Instead almost every perk offers only a flat percentage increase in damage, leading to the problem mentioned above that you never really change the way you play the game, you only gain the ability to fight the same enemies that are now a slightly-higher level. The removal of perks that really alter the way you play the game, abundant in the original Fallouts and New Vegas, and even Fallout 3 to some extent, really highlights Bethesda's baffling strategy of cutting good ideas from the original games that were handed to them on a silver platter. You really get the sense that Bethesda is bitter at how competently made New Vegas is, and decided to rebel by going the opposite direction in terms of depth as part of some misguided attempt to prove that they can also make a good Fallout game. I really cannot stress enough how badly this game fails as an RPG.
I just... The best part of Fallout 4 really is that Obsidian might get to make a competent game using it as a base. If not, Bethesda has wasted everyone's time and showed honest to god contempt for hardcore fans of both Fallout and Bethesda games in general as they staunchly refuse to improve on any aspect of their games despite how well the company is doing, and continue to slowly cut away anything good that remains.
