Oh my Gawd the English dialogue and voice acting. It's terrible and it never gets out of the way. No one EVER shuts up, least of all your character.
The lead you play is also designed and written as an uber-chad. It's like a non-self-aware Duke Nukem that takes himself seriously.
It's a shame that such an intriguing world filled with beautiful set pieces can't be enjoyed because you're constantly listening to yourself poorly delivering bad lines to your hand.
