Most of the criticism in the video is solid and well intentioned. Still, I think the guy behind Yesterday will chimp out all the same, especially when Warlockracy joked that Frontier is a better mod(it is, at least in the aspects mentioned in the video).
What I don't agree with however is his assessment of Van Buren story, lore and characters. I suggest watching the Van Buren design document overview by Retcon Raider, there is a whole lot Warlockracy doesn't go over either because he personally doesn't like Van Buren or because he misunderstood the concepts.
Good example is the big bad, Victor Presper: He is compared to an evil wizard who wants to destroy the world using magic and when his motivations are outlined, he is simply described as a bitter moron, much like Elijah by Warlockracy. That can't be further from the truth, Presper decides to nuke Mojave, Arizona and New California since he has seen first hand what (((Brahmin Barons))) did to NCR after Tandi was assassinated(in the Van Buren timeline). This is basically him going scorched earth, literally, on a government he no longer believes in, and his disillusionment leads to him going further than that and proclaiming that nobody in the surrounding area is any better, and it would be better if he hand-picked who would survive a second nuclear holocaust with him. This is also why he has so many men with him, there are others within the NCR who see just how corrupt to the bone it is and see Presper as a better alternative even knowing full well what he is planning. He is seen as the smartest man on Earth, and if you pick an ending where you freeze yourself in Boulder Dome, it turns out that without your involvement his plan works and you wake up in a new world ruled by him...altho the ending is vague enough to never mention what he does with you once he awakens you from your pod. You might think this is going too far, but remember that this isn't the same NCR from New Vegas we are talking about, this one is much more corrupt and without a big threat like Ceasar's Legion to keep them in check. Also, the "golden years" were cut early and the country went downhill much faster than in the canon timeline.
But nope, let's throw all that out and call him a dummy, maybe throw in a little skit about him becoming a #DarkWoke commie larper because radical extremists, am I right fellas? The locations aren't better, he describes each with one to two sentences that don't go into any details over the location, it's history or conflict within them. Mesa Verde is described by him as "a tribe with painted people". He didn't mention that the tribals are Ciphers, who are obsessed with technology to the point where they draw mathmatical formulas on cave wall and have memorized complex schematics they can recreate by hand, which their ancestors had to condition onto their children by necessity since the computers that held the data malfunctioned and data was lost, only option was to make their children learn all the knowledge and pass it onto their children. Today, Ciphers still pass down this knowledge but have no idea what any of it means, being tribals and all that, making them ignorant but also fascinated with all things of technological in nature. There is also the conflict with the Vipers nearby send by Daughters of Hecate(fanatical female cultists who control the local tribes thru trickery and subterfuge), who want to literally starve the Mesa Verde citizens off, and you have to intervene. One option to do so is to help them build a "laser cannon" which is just a common laser pistol that is 50x bigger and more powerful(they know the schematics by memory but have no clue what any of it means, remember?) so you can literally blow Vipers off the face of the earth. This is just one location in the design documents, which in the video is summarized as "tribals that wear body paint".
