I recently just replayed both of X’s games and VII, because hey, they are my favorite Final Fantasy games. With the exception of direct sequels, most Final Fantasy games are completely independent from each other. That’s not always true—we have the Ivalice Alliance games such as XII and Tactics that both take place in the world of Ivalice, albeit a thousand years apart from each other. But unless we’re specifically told otherwise, it’s always been safe to assume that the Final Fantasy games have no impact on each other. At least, that was the case until X-2 happened. During an interview for Final Fantasy X-2 Ultimania, Nojima confirmed that X and X-2 are prequels to VII. While the stories in the games are still more or less independent from each other, this connection allows for some interesting social and religious implications, specifically for the Al Bhed.
Final Fantasy X has so many religious themes going on. Of course, that’s not surprising when you establish a world heavily ingrained with religion and base that religion on three very popular faiths and ways of life: Buddhism, Shintoism, and Catholicism. Sometimes, FFX feels as though it’s all over the place, as if the writers couldn’t figure out which religion should dominate. But for the most part, and excusing any plot holes, Yevon seems like a solid faith that I could see existing given certain circumstances.
But like with all things religious, an afterlife must exist, so it’s only natural that Final Fantasy X makes mention of the dead. In fact, if there’s one aspect more dominating than religion in the game, it would be how the dead affect the living. And also like with everything else involving this game and my over-thinking things, yes, I found some more plot holes.
