Okey dokey chaps, let's run this down.
Gods/All Powerful Beings come down from the sky and terrorise the planet, with the intent of wiping us all out and starting again.
Here's what happens.
I find a sword that's bigger than my body and somehow develop the strength to wield it accurately.
I gel my hair into an implausible position.
I team up with my best friend (who's not as good a fighter as me, but he's well good with magic, which has been discovered only when the gods reach Earth but he's still well good, probably down to his command of the internet) and seek out my childhood sweetheart despite the fact I'm in a happy long term relationship and I've not seen said woman in years. She... I dunno. Likes fist fighting or something.
I then go back through my life counting off people I know and where I've met them and if they fall into a pattern I wish to refer to as the Final Fantasy Fractal based on where I've met them, their personality traits (I.e. stoic, womanising, out for revenge, etc - all the usuals) and their fighting styles, and assimilate them into my party.
One of them is an engineering student and he has, against all expectations and odds, built a FUCKING AIRSHIP in his spare time. We all bundle into the airship. Let's call it, I dunno,
The Overcompensator. He's an engineering student, he's not gonna get laid

(unless he is the "Womaniser." Then he will actively pursue getting laid and always get it, but never call them back).
We bundle into the airship as mentioned, and fly around the world fighting lesser gods to gain power and also a large, faceless pro-industry organisation that has aligned itself with the gods in the hope that they will be spared. They are secretly intending to doublecross their benefactors, but about halfway through the third disc the would-be doublecrossers are doublecrossed, and are wiped out to a man, who goes into hiding. This man is... I dunno. Bill Gates or Barack Obama would probably work best, considering Steve Jobs is probably dead by now and Gordon Brown's hit the lynch mob.
No wait, it's Sarkozy. He's the most evil man on the planet. Bastard.
By now we've reached the fourth disc and are flying our airship to... let's say Antarctica, either that or one team is going to Antarctica and the other team is in the Arctic because we need to fight the gods at both poles simultaneously, and we have a massive debate in which we tell them the human race deserves to live and they submit otherwise, and we then fight them in a climactic battle, which near the end involves me using a supermove I've only just learned which allows me to inflict 20+ hits at approximately 9999 damage each in ONE TURN.
We win, of course, because we're the heroes, though it's a much tougher job for the team that doesn't have me in it (all but one of them is "fainted" at the end of their battle), and are treated to a final cutscene that is ridiculously long and only mildly interesting - let's call that the rest of our lives.
All this is set to a beautiful score by the wonderful Nobuo Uematsu.
That is what would happen.
