Never claimed to. The problems with the setting of Fallout 3 don't require me to speak for anyone, because they aren't subjective. The fact that there is a large population of people in an environment without plants or clean water two hundred years after food production came to a screeching halt is an objective flaw in the setting of the game. You can gloss over that subjectively if you don't care, and that's fine, but it's a flaw regardless.
I wouldn't pin any post-nuclear war survival strategies on what you've "learned" from Fallout 3. Just saying.
This gets back to the difference between objective and subjective. You are, subjectively, entitled to feel how you want about the setting and gloss over problems. That doesn't make the problems any less real.
Note, please, that I'm not demanding scientific accuracy. My suspension of disbelief covers water remaining dangerously irradiated for 200 years, big talking robots, and laser guns. My suspension of disbelief does not cover problems with the infrastructure of the society that are brought directly to attention by the game within the context of the game. To mention a couple quick examples:
1. Tenpenny Tower. The game goes out of its way to explain how citizens of Tenpenny Tower are wealthy, and pay rent to Mr. Tenpenny for a safe, luxurious place to live. These problems wouldn't matter, except that the game calls the user's attention to them. Where do the tenants of Tenpenny Tower get money? It can't be through producing anything of value, they don't. It can't be trade, since no one is let in. So it must be an endless money-sack they store conveniently in their asses. Where does the food they eat come from? This problem applies across the board, but is worst in an isolated community that doesn't do any trading or scavenging.
2. Megaton. How the hell does Megaton have food, water, and electricity? Scavenging for food might work in a setting 20-30 years after a nuclear holocaust, but 200? Assuming the food lasts that long without going bad (it's science fiction, I can assume that), the Capital Wasteland has a fairly large population who, presumably, had parents who needed to eat to survive and have kids. Was there just an enormous food factory nearby that still feeds everyone to this day? If so, it contradicts Moira Brown's food scavenging quest.
It can't really be hunting, either. There isn't enough game nearby to support even the Republic of Dave, so it's hard to buy that it supports the population of Megaton. Further, there is no plant life outside of the Oasis (a fact that, again, is brought to the player's attention actively via radio announcement), so even the mutated animals shouldn't/couldn't exist. What do they eat? People? Is the entire food chain dependent upon 200 year old Fancy Lad Snack Cakes?
There are farms in Middle Earth. Argument defeated, try again. Though even if no farms were mentioned in the books or shown in the movies, it isn't a nuclear wasteland so certain things (such as food, water, and the characters pooping) can just be taken for granted.
Fallout 3 isn't a bad game, it's an above average game that suffers horribly from bad writing and setting design.
No. The things I've mentioned as being wrong with the game are things wrong with the game. Something as obviously stupid as breaking a GECK to finish a water purifier isn't just bad writing in my opinion, it's bad writing in fact. The same goes for President Ebil giving the protagonist the plot-device-poison, despite it being the crux of his entirely illogical and nonsensical master plan to kill everyone and the fact that you are railroaded into actions that give President Ebil no reason at all to trust the protagonist. Objectively, Fallout 3 had a poorly constructed plot. You can -ENJOY- a bad plot, lots of women enjoy romance novels that are objectively awful (*cough* Twilight). That is where preference and opinion come into play. Something being enjoyable does not make it good.
Stop apologizing. I stand by my assertion that this isn't a matter of preference. You can prefer ruins to rebuilding, and that's fine. That doesn't mean Fallout 3 executed the ruined post-apocalypse setting well.
