Hahaha. While I feel like far too big of a misanthrope saying this, I think I understand why they took this route perfectly.
You see, the feature that dominates the European edition's boxart is the crane. Stylistic; noir; thrilling. Excellent from an art point-of-view.
The thing that dominates the American boxart is a woman. More specifically, a woman's breasts. More specifically, a woman's breasts, slightly glistening with rain.
That's probably why they simplified the typeface. Also, there's more light on the left side of the picture, as well as a lot more activity. Can't help but accuse the boobs.
