My problem with the trailer is that their latex outfit doesn't make sense in the series. Hitman games always had sexuality but this is just simple fan service. It's just out of place for the games. My biggest problem with the trailer is the shooting fest. Hitman games are about killing some stealthy and not just agent47 shooting everything that moves. I hope it's just the trailer and that the actual game won't be like that.
Anyway, the media has always done this. Men and women, we're always told how we should be. There is always a standard type. Things that society like, or at least the majority might enjoy. If the things that is generally considered how we should be change, then the depiction of men and women will change as well.
As an example, in western games men are often portrayed as gritty, bulky and badass. Those are the type of men that is considered to be well like by the target audience, so they use them often.
In Japanese games, the guys are often boys which look young and feminine and pale. There is a different target audience in Japan, different type of men are considered to be good characters, so they use them often.
Companies want to make money and they want the lowest risk possible. That means, if they have something that works, they stick to it. These depictions of men and women work for now, so they always use them. If suddenly they sell much less with these types, they'll switch to something else that works but there will always be specific types of men and women which will be used most.
Bear in mind that this is just a generalization. It's just how the majority of companies act and what the majority of the target audience likes.
What I'm hoping is that as games become more popular and the companies will have a more diverse target audience, the games will also be more diverse.
Personally, I don't have that much of a problem with the depiction of the genders in that trailer, it's just that the same type is used so much. I don't mind it when there are sexy women and badass men beating each other up as long as there are enough games where the genders are depicted differently but at the moment that's not the case. I like playing games like Saints Row and Gears of War, as long as there are games like Half-Life and Zelda.
I just want more diversity
