In one of the games I worked on, there's a section where the main character examines a ladder several times. In Japanese, he makes a number of jokes that play on the word hashigo, which means both ladder and bar-hopping in Japanese. Specifically, he makes a series of jokes about going out drinking with someone who gets progressively more and more sloshed.
In English, obviously, this would seem like absolute nonsense if translated literally. I did what any other editor likely would have done, and wrote up a series of jokes in English that had to do with ladders, such as “Ladder? I don't even know her!"
Admittedly, this is something of an extreme example, but I've chosen it because it illustrates what I feel is one of the core precepts of quality video game localization: entertainment is more important than literal accuracy. A translation that captured what was being said literally in Japanese would have been, at best, humor of the absurd, and at worst, complete nonsense. . .
