Man, I really don't like how Fallout has power armor or combat-application lasers, because they definitely didn't have those in the 1950s. :^)
In case that was implicitly directed at my comments, the design of those fits the aesthetic requirement I described earlier. I didn't call for a restriction to 1950s-only technology, that's not what Fallout is, but rather the strict application of 1950s-like modern and contemporary sci-fi art design to all 2077+ technology.
That's why Vertibirds are great in their stocky, pulpy design, down to the name, and hypothetically copy-pasting modern V-22 Ospreys would be terribly missing the point.
It's all about looking at 2077+ through the lens of the 1950s. If something did not exist in that period (i.e. laser rifles, assault robots, power armour), imagine it as if thinkers of the time would've envisioned it. It's something the Fallout series does pretty well most of the time, but sometimes slips for no good reason. Taking the Desert Eagle's unfortunate example, wouldn't it have been better if the concept (high-calibre semi-automatic handgun) had been visually designed through the aforementioned lens? New Vegas' M4 (called the Marksman Carbine, I think) would've looked more in-universe if it had been more similar to the standard assault rifle, with more wood on it and less picatinny rails, for example. I mean,
this looks completely out of place in the Fallout universe.
I trust most of you can grasp what I'm talking about.
