Everytime I see someone cosplaying Fallout I immediately think they are paid shills to promote Bethesda games. Rarely I see someone cosplaying something from New Vegas and literallly nothing from original games. How can you make a cosplay of a shitty game? Does Fallout really have this wide audience for cosplays? Maybe they are all legitimate but still I think it looks fake. How can you like a game where you just loot trash in same locations? Warhammer, StarCraft, League of Legends, Dota, Stalker, all of those have some artistic thought, Fallout 3 and 4 are terribly mimicking Fallout 1 and 2 so why I don't see someone in blue jumpsuit with 13 on his back? Why they promote those bad games?
Bethesda don't care about the lore of their games, this has been proven many times over with recent iterations of both Elder scrolls and Fallout. And subsequently, to be a fan of those games. You have to either be willing to completely forgo the story in the games and just run around mindlessly killing things, but then why not play something thats better at that?. Or you don't care about lore or the established universe either.
I don't think it'll be long before Bethesda announces the Fallout universe has been 'rebooted' and the two original titles never happened.
I'd say they care about the elder scrolls quite a bit though, it's just that the elder scrolls universe doesn't have a proper idea of what is canon. Also, it's been made clear before that every elder scrolls game is just a historical recount that may of been subject to editing by some unknown party.
In terms of Fallout: You can argue their changes are bad, terrible even, but I don't see any real errors they've made. They've retconned a few things, but it's their IP now so they're allowed to do that. Unless there's something I'm not aware.
Where to start? I suppose first of all there's the monetary system employed in Fallout 3 and 4. The bottle caps.
The system of trading with bottle caps was first started and used by the traders of The Hub on the west coast, it's unlikely that it would've spread as far as the east coast, in the time allowed. Speaking of spreading that far. What about the super mutants? They have no reason for being on the east coast either, and certainly not as numerous as they are.
And why is it that many of the super mutants in Fallout and Fallout 2 were intelligent? you could even reason with them.
In Fallout 3 and 4 they're nothing but pseudo-orcs who want nothing but to murder and maim and collect "gore bags". Thats not at all how they were established in the original games, they had purpose and reason for doing what they did, why would they suddenly turn around and become something like what they're portrayed as in Fallout 3 and 4.
It was also clearly established that the FEV was a "shifting-absorptive megavirus" that due to it's transformative properties and rewriting of the genetic genome completely transforms and cures the victim of any illnesses the victim might have contracted in the wasteland, including cancer from radiation poisoning. But in Fallout 4 we learn that "The Institute" has developed a "cure" for FEV, that can reverse the effects of the virus. This effectively means that they can cure anything with FEV, due to being able to completely reverse the ill effects that it causes.
But after having had this developed they seemingly shut down the "FEV Lab" and left the cure there. It's also revealed that The Institutes director is dying of cancer, despite being made the director due to having 'clean genes' without any mutations caused by radiation. So not only do they have the cure to cure their director, they also have the cure to cure him of the ill effects that it would cause. And this is the same guy they all speak of in reverence, the same guy they based all their third generation 'synths' on. But they forgot that they can cure him, and probably the director would know what they've developed over time and what resources are available to them, but he forgot as well.
Concerning artificial intelligence, it's established in Fallout 1, 2 and even 3. That if you have an artificial intelligence, it's a big fucking databank, that takes up a lot of space. But in Fallout 4 anything can have an artificial intelligence, even a mister handy. That was never inside the institute or was upgraded with their "advanced" tech.
In the original games The Brotherhood of Steel is this reluctant faction that only allows you access to their bunkers after having sent you on a suicide mission, that you, despite their best efforts, survive. Then you learn that the Brotherhood of Steel not only wants to preserve old age tech, they're also creating new tech based off ideas from pre-war technology.
Their most holy ideals concern the preservation of all advanced tech, both for the future, but also to ensure that it can never be used again by anyone who doesn't understand the implications of it. You get to talk with General Maxson, the alleged Founder of the Brotherhood, and these ideals.
In Fallout 3 the brotherhood of steel is this joke of a faction that just wants to 'rescue' the wasteland. It's full of goodie-two-shoe non personalities. But a few years after the events of Fallout 3 where the Brotherhood saves the wasteland of D.C from the enclave that wants to kill all mutants.
The leader of the eastern Brotherhood dies, and a new leader is elected, by the same people who fought the enclave for reasons previously stated. They elect a leader who wants nothing more than to destroy all advanced tech and purge the wasteland of all mutants. And he's Maxson's great-great-great-grandchild.
And another issue, new power armor keeps on cropping up with each new installment of Fallout. Despite it being established that power armor production was only kicking into gear when the war started, that's what makes it so rare. Not a lot of it was ever made, never mind the time they'd have to spend on research and development to iterate upon it.
There's many more issues, but I don't feel like going on, it makes me sad to think about it.
