As someone who believes both in equality and freedom I have been thinking on a growing trend where if something is made sexy it is then accused of being sexist?
I do not agree with this as sex is the one area where there is a genuine physical difference between both men and women and this would therefore lead to a difference in the effort to create sexual appeal for both men and women.
Threrfore the games industry will often include highly sexualized women to appeal to men as it can often have an impact on the games popularity (How many people bought Dead or Alive Volleyball just for the gameplay?) but will make little to no effort to provide highly sexualized men to appeal to women as it will likely have no impact.
I will agree that having female characters that appeal to men and not women may put women off from playing the game. But this is simple appealing to one demographic as opposed to another which all games do in one form or another as you can't please everyone.
As was said by Herbert Bayard Swope "I can't give you a sure-fire formula for success, but I can give you a formula for failure: try to please everybody all the time."
What I view as the primary problem is that female characters are on average far less developed than male characters and their sexualized appearance is seen as the cause.
I would also like to point out that while I don't view games having sexy characters as inherantly sexist I do agree that it can sometimes be determental to the gaming experience.
