They are that, but no, I compare them for their similarities, not the shared differences from Fallout 1 or 2.
Of course not.
FO2 started the pattern of deviation from the source... then Tactics, then FOBOS, then FO3.... (see below)
They certainly did... funny that. Ever think that WAS one of the mistakes? If Fallout was to have been 50's themed in their present... you'd think they'd of had 50's greaser gangs instead of the Khans, and the Mysterious Stranger would have been Fonzie instead of Max. Nothing in FO was 50's themed that was not pre-war. :shrug:
What similarities are we referring to? Again, are they not only aesthetic? You've admitted yourself that you haven't even played BoS, and you claim to draw non-aesthetic similarities between them? With no experience with the game, why bother trying to compare them? You may as well write an essay comparing and contrasting the mindset of two separate authors based on their autopbiographies, without actually reading one of the autobiographies and claiming they are similar because their books are both hardcover and green.
Then, again, what are some differences that aren't merely skin-deep?
If I'm interpretating your statement correctly, then I assume you are unsatisfied with all the Fallout games but the very first one? At least I can draw a connection between Fallout 1 and 3 in the depressing, serious atmosphere, no?
Ever think Bethesda might have actually fleshed-out what Black Isle attempted in a way far better than Black Isle did, yet still desired? Nothing in Fallout 3 except Pre-War stuff was very 50's themed, either, but all the Post-War stuff was based on the abundant amount of Pre-War objects. Vault 101 still had that 50's theme, but it was preserved from before the war. Music had a 50's theme, but it was also mostly before the War (the exception being Agatha). The Enclave was stuck in its Pre-War state of superiority as they had for 200 years, but with a greater emphasis on exaggerated 50's patriotism. Liberty Prime was a Pre-War, anti-communist machine. The D.C. ruins are still Pre-War. Andale is an internally preserved, 50's style community with a twist. Bethesda placed the game in the East so as to be able to make the gameworld more based around some experimentation, including the exaggerated 50's theme, without clashing with the West. The East was hit hard enough that all people had to go by after the War was a large amount of 50's, Pre-War culture and technology in this urban area. Of course they would scavenge things. What was the point of having the 50's theme last in the originals until 2077 if it was very rarely referenced in the game? What fun is poking at exaggerated 1950's style American patriotism, anti-communism, and visions of the future unless actually having an impact? For the remains of a civilization stuck in the 50's, few things in the originals reminded me of 50's culture/paranoia. What's wrong with giving some actual variety to the tone of the series and exploring a concept Black Isle left unexplored? I used to think "Shooters are all the same, so why don't their fans want change like in RPGs?" Now, I still appreciate the variety among RPGs, but certain, notoriously-divided fanbases seem to want to leave things as static and as stale as most shooters.
