Speaking of the Brotherhood. They're a pretty good indicator of the modern gamer's mindset. Especially when you're ordered to eliminate the Railroad. A bunch of people felt guilty over doing it but acted like they were following orders as if there was no other choice, Call of Duty style.
It's a very ironic thing to see - people actually playing their character into a "I was just following orders" role and making up justifications and defending their actions. Joining a selfish, xenophobic group, saying that they were trying to save the Commonwealth from synths, justifying their massacre of the people who helped them reach the Institute (and their son). Mindlessly following instructions. And you see it everywhere - in Reddit threads, Facebook comments, and Bethesda forum pages for the game, everyone quoting the Brotherhood as if they're a CoD-like "good" faction. "Ad Victoriam", over and over again. Sure, it's all a joke, but it does speaks a lot to psychology.
"Dang, I have to kill the Railroad! But those guys helped me... Oh well, I've to do it to continue the story, I'll do it. I feel bad about it, but I'll do it anyway, because it's the right thing. For the Brotherhood!"
It felt outright meta to me hearing it in the commentary of YouTubers playing the game on their main playthrough. Especially in a game where you can stick with other factions for a different ending. Reminded me of Spec Ops: The Line, except this time the game blatantly tells you that you can pick another path, yet the player goes with it anyways. That makes the irony all the more sweeter.
In short, everyone feeling like the hero sticking with the Brotherhood of Steel tells us a lot about modern gaming attitudes. A lot.
