Also, both fallout and fallout 2 showed humanity 's efforts to get back on its feet. The second game had places that looked...nice even, like vault city and shady sands 2.0.
In nu-fallout everyone turned into a lazy hobo that can't even be bothered to patch crumbling walls. For some reason.
Yeah, Fallout 3 is just ruins and rubble everywhere, 200 years after the war. Realistically, most of the safe-to-visit areas would be cleared of rubble by now, new buildings would have been erected with salvaged old bricks or concrete blocks rather than the simple wooden boards and sheet metal shacks we find in Megaton, and there'd be plenty more farming than we see in that game (is there even any farming at all? How do the communities in Fallout 3 produce food?).
Fallout 3's terrible assets are also the greatest weakness of New Vegas. NV built up proper societies and settlements, but most of the buildings still look like they haven't been maintained for a century due to Fallout 3's terrible textures. The city of Vegas should look a lot cleaner and more well-maintained than it does. It's a fucking tourist trap, after all.
