I enjoyed Fallout 3, and it certainly showed a lot of love for the Fallout universe on Bethesda's part. It wasn't a bold addition to the series though; their conservatism in holding to the feel of previous games made a lot of the setting feel empty and unbelievable.
Consider these elements:
a) Vaults
b) The Brotherhood of Steel
c) Supermutants
d) The Enclave
e) Water Supplies
These are major, iconic features of the earlier Fallout games. FO3 centered almost entirely on them. That should make it a great Fallout story, but it doesn't. Because the original games told original stories, and Fallout 3 retells those stories with some twists. It stretches lore and credibility for the sake of forcing the old factions together again. In a way, it was probably necessary; with the series dead for so long, Bethesda needed to announce that Fallout was back, without deviating too far from the old lore. And if you haven't played the earlier games, Fallout 3 captures a lot of the cool iconic ideas that were in them, and shows them new to you, which is probably way cool. But to me, they're old ideas -- and neither of the original two Fallout games would be remembered if they were full of old ideas.
New Vegas has the creativity of the originals. Instead of telling stories about vaults and mutants and power armor, they told new stories about Mr. House and the Legion and the Boomers and they continued the unfinished story of NCR's expansion. Just like the originals did, New Vegas presented a world full of surprises, and got me thinking about possibilities and wondering about the future of the in-game world.
My biggest annoyance? It's has been 200 years since the bombs fell in game. What have we, in the real world, done in last 200 years? Electricity, flight, Space Travel, micro-computers, advanced robotics, ect. What have the people in Fallout 3 done? Built tin shacks.
To be fair, they probably are spending a lot of extra time puking from the radiation poisoning. Probably puts a damper on progress.
Unlike the Californian Wasteland, where everything's hunky-dory and radiation free?
No. The people in FO3 are just total fucking morons. They're concerned with stupid shit like bottle collections, history museums, or worshipping a bomb. If they put their heads to it, they could've made the next NCR (which grew out of a primitive farming community, btw.). They could've even moved into one of the more functional vaults, or simply looted them for tech. Instead they just wallow in their own trash and worry about irrelevant crap.
Yeah, this. Add onto that the fact that there was still food in the vending machines. Because not only do potato chips keep for 200 years but nobody in those 200 hundred years thought to loot the vending machines that are a short walk away from what passes for major settlements. Oh and the prewar guns and ammo still work and are readily available.
FO3 felt more like it's setting was 5 years after the war. Pretty much the only thing you'd have to change about the setting would be renaming the white hats in powered armor from the Brotherhood of Steel to the Maryland Marine Forces Reserve and you are good to go. And frankly, that would be a pretty good lore change in it's own right as the Brotherhood of Steel apparently received a lobotomy in between FO2 and FO3.
Also, this, including all the complaints in the quote pyramid here. This drove me crazy. Fallout 2 showed a world that was growing and rebuilding in the wasteland. Fallout 3 presented a world that was actually regressed from that, back to Fallout 1, so frozen in time that even the plot is based on the completely implausible idea that the river is undrinkable from radiation, 200 years later. I'm very glad New Vegas came out, because it corrected what would have been a sad "new canon" -- sequels so loyal to the originals that the world stops changing, and is permanently just a couple years after the bomb.
It reminds me of Star Wars. Love the prequels or hate them, they brought the same sort of discovery and innovation and grandeur that the originals had. When most of the expanded universe made only small, safe changes, and told stories using the well-trod paths already beaten out for them, George Lucas told stories where everything was new -- gungans who fought with spears and insane shield/grenade energy technology, stormtroopers as all clones of Boba Fett's father, Yoda fighting with a lightsaber, even those stupid cutter droid missiles. A lot of it was pretty cheesy, but Star Wars has always been like that, it was just cool and new enough to forgive. Lucas's own addition to his old canon was more true to the originals than anyone else could have been, because his prequels were creative, original, and full of surprises, just as Star Wars was always supposed to be.
