Honestly, it’s a Western media thing. Pretty much the only mythology most of us English speakers are taught is Greco-Roman. In past decades, efforts to branch out were often shallow. Things are getting better, there’s more stuff coming out drawing from indigenous or African or South Asian mythology or whatever. But it’s taken some time.
Video games have been mostly made by white dudes, after all. They’re exposed to white dude stuff.
