I get the problems people have with sexualized characters. However, I do not think this game is the best example and as such I think the debate's focus is wrong.
The characters in this game are all overexaggerated in one way or the other but usually so much that the aesthetics are not appealing for most persons, at least not in a sexual way. What this means in my opinion is that people who see this game are instantely saying: woah, look how exaggerated all this is. They will usually not say: aww, way too sexualized.
So for an argument that too many games are for pubescent boys, this game is not a good example.
Or to put it more bluntly: The game doesn't take itself too serious, commentators shouldn't either.
Jason had enough time to make these articles about Dead or Alive where it is more appropriate. [although I dont agree with his arguments anyway]
