The games are not about the resource wars... The resource wars are just a small background detail to explain why the world was at war 4 generations before the first game happened.* The games about the massive Resource Wars that involved destroying Canada?
Also, Canada wasn't destroyed in the classic game's backstory until the bombs fell and supposedly destroyed the entire world (never confirmed in the classic games). The US annexed Canada, but it was never said, mentioned or implied that it was destroyed before the apocalypse.
Here we see it again, people who think Fallout was about the bombs, the apocalypse and what happened before that, instead Fallout was about what happened almost one century after the bombs fell (and more than 1 century by Fallout 2).
I think this is because Bethesda focuses so much on the pre-war world in their games, which is fine for those games and Bethesda's vision for the franchise, but it deviates from what classic Fallout focus was on. The problem I have with this is when people who didn't play the classic games or (didn't understand them because they didn't think about it) say that the classics were about the past, the war and bombs just like Bethesda's Fallout.
It's not the games, it's the game. Enclave only exists in Fallout 2, not in the first game. Also, I'm pretty sure that the oil rig base was for (at least) three reason:* The games that have the Far Right government based on an OIL rig? (symbolism much?)
The first reason is that it's an isolated place in the ocean that would not be targeted by nukes.
The second reason is because it's easy to explain how they get food and water, the ocean can provide a lot of food and as long as they have desalination machines, they have virtually infinite drinkable/usable water.
The third and most important one is to explain how the Enclave still had enough fuel to fly and make refuelling stations on the mainland for their Vertibirds. This way they wouldn't have to come up with an explanation for why the Vertibirds could fly around all over the West Coast without any other fuel source.
Repeatedly? I kindly ask you to give me five or more explicit examples (not vague and open to interpretation) of that in the classical games. I would love to see just five times where the classic Fallout games explicitly told us about the destructive nature of consumer-focused 1950s America. The 1950s aren't even mentioned in the entire games and neither are the games happening in the 1950s.* The games that repeatedly drill home the destructive nature of consumer focused 1950s America?
The only thing mentioned was that the world had run out of most resources, and that led to wars in the (mostly forgotten) past. That information is (once again) just a tiny background element that is said once or maybe twice in the games and that's it (because, once again, classic Fallout games weren't about the past, they were about the present and future of that post-apocalyptic area). It's not important or relevant for the characters or factions in those games, it's not repeatedly mentioned or talked about, it's not repeatedly shown either. It's just a little footnote in the backstory of that world.
