God of War III
Yeah. There's no room for argument with this.
There really is no other word other than epic that does this opening justice. The music is relentless in heightening the tension and scale of how massive and world-shattering this battle is. Riding Gaia and heading a legion of Titans to shatter the pillars of Olympus is sort of the definition of all things Greek myth is known for. Kratos, nearly molecular in size compared to the Gods, gives no fucks in this opening.
