The main story of this game is threading on dangerous religious grounds mainly because of when a specific groups of people (beast tribes) summon their gods and we go there, kill their gods and put those people in their place after they get brainwashed (tempered) by their respective dieties. This kind of story is very dangerous in religious countries and square enix will get in legal trouble if they continue this type of storyline. This game has now gained a lot of attention and popularity. Its no longer hidden by WoW and the storyline will get a lot of attention now all over the world.
Basically the story of FFXIV is saying that "Don't worship your gods or else we will kill your gods and then put you in your place. All the gods when summoned turns evil and brainwash (tempers) their people".
I was also shocked to see that when a particularly important NPC told me all the 12 gods of the civilized races of Eorzea like Rhalgr, Halone, etc can be summoned if we lavish them with crystals and gorge them with ether. And when summoned the gods will turn evil (just like the beast tribe gods) and will fully brainwash (temper) all their worshippers. This type of storyline may have worked 15-20 years ago but nowadays in this new generation people will not tolerate it.
I won't be surprise if the storyline gets censored in the coming days in majority of the countries.
