I was thinking about resurrecting this thread myself, but I realized it had been after I started getting "likes" for posts I'd made in it.
But yes, not everyone has Twitter--I don't--or Facebook--I also don't have that--so, we need to see Lady Inquisitor in the trailer and on the website. And it can't just be as an afterthought. She needs to be prominently there. No five-second mini-clip, no tiny thumbnail hidden somewhere on the bottom/side of the page.
The ambiguous box art is a start, sure. But we see Gentleman Inquisitor everywhere, and people will assume Box Art Inquisitor is a man, because they've seen no lady inquisitor anywhere, except if they happened to be following Dragon Age on Twitter. Which is something that pretty much only existing Dragon Age fans are likely to do, let's be honest. People seeking out information, who have never played a Bioware, or a Dragon Age game, before, are going to look at the website. Many will not be scouring the Internet for news articles--and some women who might not want to be exposed to the horrible comments sections on most video game news sites/articles (which are notorious for being filled with misogyny and general idiocy) may avoid online articles entirely.
Whatever else you say about it, YES, representation of women in games is a big deal. It's a VERY big deal. Up to 40% of gamers are women. Yes, that likely does include hardcore gamers. I've run into lots of women who game when I was playing ME3 multiplayer on PC. There are lots of us here on the forums. You can argue that women are more likely to go to gaming forums, but I have found that, due to the hostility that usually exists toward women on gaming forums, the opposite is more likely to be true. So, it seems to me that Bioware may actually, honestly have a larger-than-normal number of women who are fans and players of their games. No, it's not just the romance. When I first played a Bioware game (my first one was Dragon Age: Origins, after reading about it in Game Informer and getting excited enough to preorder, so I was late to start on Bioware games), I had no clue there was romance. But I did know I could be a woman, and that was very exciting news. DA:O wasn't what I expected from what I read in that preview article. It was better. At the time, it was the singular best game I had ever played, and being able to be a woman in it made it so, so much better.
So yes, it's important that it be made known publicly, in as many places as possible, that the player can choose a woman as their Inquisitor. Choosing other races is also important information, but since there are no elves, dwarves, or qunari in the real world, whereas there ARE women--who are actually slightly more than half of the population, with a sizeable number of gamers among them--women need more representation in mainstream marketing.
I am personally straight, but I will also go out on a limb and say that there are probably LGBT people who would like some marketing thrown at them, too. Some mention on the website, or trailers, that you could pursue a same sex romance, might be welcome to them. It certainly didn't hurt with the Sims marketing when they did something like that. Yeah, there will be jerks who will hate it, but... there are jerks who hate women, too.
