I think it is quite simple. This post is my opinion, and although I am pretty sure about this and may appear dogmatic, it is my opinion after all.
RPGs, movies, books, usually rely heavily in their ability to makes us identify with their characters. And once we have that little identification going on, live adventures, try new things, know new people, explore new places.
That is why commander Shepard needed to be human. If it were a Krogan, I would have not identified at all with nobody there at the begining, it would have been tough to like.
That is why Act 1's plot of Dragon Age 2 was terrible for me (lack of adventure whatsoever, it was like working after work).
That is why we want epic adventures, and you almost never see a videogame of "normal life".
The marketing of videogames is tricky because it is difficult to reach the gamers. If we talk about adverticing, posters, graphics, etc, usually you can only show a single image to the gamer, and try to attract him/her with that image. For that reason, you want to attract with that single image as much % of the viewers as possible.
How would you accomplish that?
1) With a badass male inquisitor
2) With a badass female inquisitor
3) With the logo, tribal stuff, something that only understand people that already know about dragon age
4) With a HOT male inquisitor
5) With a HOT female inquisitor
Depending on who sees the image, they would feel atracted or not. I would feel atracted by 1, 2, 3 and 5, because I already know Dragon Age. I would be repeled by 4, I am sorry.
My girlfriend would feel atracted by 2, 4, and repeled by 5.
So just ask you the question. Do they need to atract me? Hell no, I am already here, isnt it obvious I am going to buy the game?
Who do they need to attact to make the game sell as much as possible? If they only had 1 shot?
Yes, the answer is the average white straight male who would feel atracted to a badass male inquisitor or a hot female inquisitor. And we are talking about a Lara Croft, not a Female Hawke.
That is why by default, all marketing should focus on badass male inquisitors. And once that is covered and seen first, they can focus on other things.
So yes, we need more Female Inquisitor marketing. In the website, in more graphics, whatever.
And no, they should not put the Female Inquisitor in the videogame box, or the poster, or the banner of gamefaqs.
Just my 2 cents!
