Merkava, I don't think Lard is refering to a "betrayal" like the one you're thinking about. He's refering to a betrayal on the part of the writers, for making contemporary pop-culture references in the middle of the game.
Yep, exactly. I can't remember the exact references, but they were pop culture references that had no place in Lunar, much less a medieval RPG. They were jarring and didn't belong.
