I would bet a vast majority of folks would lose their faith if 90 percent of humanity were wiped out and the reaining get to live through radiation, hunger and slaving raiders.
Some perhaps, but then some would turn to it, unable to deal with tragedy such as a nuclear holocaust. You also seem to forget sadists and people with a tragic view of reality who would join a cult/religion based on their
happiness the apocalypse happened. Also, there would still probably be holdovers from older religions who would use the apocalypse as an example that they were right all along.
But hey, its all part of gods plan for you to be raped/eaten/enslaved etc.
That's comforting to most people, especially those in shit situations. The concept of an afterlife also assists with getting by day to day drudgery because you ultimately win in the end, it keeps you going.
Its a game that is meant to be fun, not some tool to introduce religion with.
There has never been any religious proselytizing in any of the Fallout games, minus the Children. However, I think it is an important aspect that should be explored
even more than it already has because a religion is the focal point of the community's culture, morals, style, whathaveyou. The development of local religion and superstition would be a key element in the rebuilding of a healthy society and there is no better game than Fallout to examine such a crucial feature.
And yes, I have never been cool with the whole evangelism thing. You got your belief, I got mine. I don't peddle my faith to you, please return the courtesy.
I get that, but having religious characters, even ones that are directly damning you to hellfire, aren't actually the dev telling you personally, the player, these things. This is an RPG and there must be world building - someone, somewhere believes these things and would tell it to your face. How your character reacts to this person and what they say depends on who your character is. I would disagree that Fallout is used as a recruitment tool for Mormons, which is what you seem to be implying.
A game meant to see life in not very black and white terms should stick to its goal. Adding religion into the mix destroys this.
But no one religion is trumpeted as self-evidently correct. The whole point is that there are multiple competing religions, each with their own hypocrisies and contradictions. Far from making it more black and white, the application of absolute morals to a wasteland still struggling to even be civilized makes for an extremely interesting dynamic.
Thing is, the most basic things people should adhere to, by and large, are things religion has no right taking credit for. The golden rule for example is common fucking sense.
Except it's not. (And to add a quip worthy of Truman, common sense ain't common.) People have a tendency to compartmentalize themselves away from the "other" that isn't their friends and family; even today with most of the world societies civilized, people ignore the golden rule all the time because the things they do wrong against others aren't a problem, in their minds. Consideration for all others takes some extremely strong community glue and perhaps rote repetition - traditional religions and strong nationalist movements (perhaps the same thing) are the first things to come to mind to serve this purpose.
The golden rule may be "common sense" but just because it's there doesn't mean most people will apply it. Thus a communal system of behavior must highlight it and enforce it, i.e. religion.
Don't go robbing and killing if you don't want to get robbed and killed. I don't need Jesus or Muhammad, or God to teach me that.
At any time there is a person who would willing kill you just to get a simple little trinket, or even just for pleasure. Involve the breakdown of civilization like in Fallout and that number of people increases exponentially. Some people do what they think is right or what they think is amiable - others think and act on what they can get away with. So not only do I contend that the golden rule does not come naturally to people, a post-apocalyptic setting would actually work against it due to the horrors of how people treat each other when unbound by common law. Thus the need of an organized basis (religion) to keep pushing it.
So in a post apocalyptic setting, every civilized town or settlement should be adhering to these rules.
But where is the fun and community building? It's one thing to have some rules that everyone follows regardless of their social input, it's another to have them actively venerating and repeating those rules on a daily/weekly basis in the company of others in the community.
I am saying it doesn't need to mention any specific religion in-depth at all. Like the Vault Tandi and the Khans came from. It mentions it was populated with citizens of a diverse racial and religious sort. No need to advertise said religion or glorify/demonize it.
How was that the intent at all? The whole point is to have unanchored morals in a sea of amorality.
