Well, i mean i would be all for that but in reality it might not be that easy. It could rely on dependencies that are proprietary that cannot be shipped or provided with the project.
It could alone be that the connection is hard coded in the game itself so instead of just booting up the server and being able to play you would now have to do something to the game itself too that it finds your server. Nothing really that cannot be addressed, I mean people could do that with ragnarok online private servers but not something your normal gamer could do.
I don’t know where I read it but IIRC religion is being used as a simple answer to very difficult and possibly uncomfortable questions: why are we here and what is our purpose?
It is fairly easy to believe that something, a god, created us instead of that the existence of humanity was just a fluke, a stroke of luck enabling us to evolve were we are now because it is just easier to grasp even if it is proven. That we evolved from simple beings into more complex organisms instead of just “being created”. Evolution creates so many quite difficult questions that it is easier to understand and believe that someone just wanted us to exist.
When someone is believing in a religion they also always have some form of " it won’t be over" scenario like when you die, there is nothing truly “the end”. You just won’t vanish and this can be terrifying for many because the following question could be, what sense does it make to live at all when our existence is just so insignificant in comparison to everything else?
So, in short, it is an easy too to make sense of things that almost everyone can understand it.
Unfortunately, things like this can and will be abused.
