I bet sometime in the future they will start censoring real life.
Equilibrium? 
Well, at least with the texture removed there won't be any lawyers out there that can use it as ammo against the video game industry.
Has anyone figured out a logical explanation for why boobs are so attractive?
*runs*
Yes. Several reasons spring to mind; firstly, they indicate fertility and the ability to succesfully rear children. Secondly, they are a good fitness (i.e. attractiveness) indicator; they are a good (and hard to fake in evolving man) sign of youth and thus virility (sag in later life). This is something that is somewhat counteracted by modern plastic surgery, although on the other hand sexual selection theory would also apply as big shows of expenditure can be of benefit (namely in the sense of "look how fit I am, that I can afford to give/spend this on frivolity!").
For reference, expensive 'shows' like this or, for example, the peacocks tail are good for mating because they are expensive 'luxuries', and thus hard to fake (i.e. they are indicative of fitness 'energy', to paraphrase the concept, because they are both expensive and maintained).
Sexual selection is (again for ref) the other selection involved in evolution/Darwinism; it refers to the excercising of females in choosing their mates and how features that are advantageous in sexual terms but neutral or not in survival terms are selected (as well as how animals with beneficial survival mutations may not see that propagate if they are sexually unattractive). Sexual selection remains somewhat obscure in comparison to natural selection because the idea of female mate choice is rather...distasteful to many male scientists and a male-orientated society (especially in the 1800s and first 3 quarters or so of the 1900s). Ignorance of this is usually a key feature of any creationist/ID arguement, interestingly. But then those types usually are sexually repressed.
