I find it funny how "It's safe/ it's about the money" is tossed out there when we talk about Women or PoC in games or films when on the small screen we're getting a well welcomed wave of diversity in TV shows and it's credited to ad companies figuring out that the best way to sell MORE of their products is by depicting the people you want to buy them in the commercials.
Not saying that all these things are playing on the same field but the reason we're getting this rising interest on the topic is because games are growing and becoming more interlaced in our lives. They're becoming more accepted as a form of entertainment so people are starting to take note of it as it's something that will help form young minds for generations to come.
I think "gamers" should at least be happy we're having this conversation regardless of how ever they feel about it. Shows that the world is recognizing (well, starting to recognize. We're still suck with "video game journalist" instead of proper journalism) this as something more than "silly shit".
I don't think anyone is saying it's a good excuse (at least I hope not!). But it's definitely a perspective that companies and those that put up the money (and take the risk) think about. Sometimes it's just dead wrong. But it's hard for them to see that. It can be very hard for these systems to SEE the future, or to realize what direction things are going. They want to bleed things dry, and it's very hard for them to move on from what they know works (and this is often why Business's fail).
That said, I think having these conversations are extremely important. I think consumers letting people know what they want, is key to getting more diverse content from them. When you put pressure on companies (like everyone giving Ubisoft shit for lack of female characters in Assasin's Creed), it puts a spotlight on them that can effect their bottom line (and thus make them see it as a better business decision to be more inclusive).
