“Please note this isn’t a design decision or something we can reverse. It’s a legal (or as good as legal) requirement to sell the game in that particular territory,” the announcement reads.

“It has come to our attention that the North American edition of the game was submitted (by Eidos) to the ESRB without any server-side censorship: full blood, full fatalities, breasts with nipples, not full nudity.
The ESRB reviewed our application and gave us a rating of Mature 17+. The full rating with descriptors has not yet been publicly announced but will be posted on the ESRB web site on 13 February 2008.”
