As long as we're being so loose with the word agenda, The Last of Us (the first game) had an extremely prevalent, heterosexual male agenda.
The game is about Joel's struggles to protect the women in his life. His daughter. Tess, and finally, Ellie. This is a plot that appeals largely to the sensibilities of straight men or fathers. I seem to remember a transgender reviewer getting shouted down for pointing this out (in a 9/10 review btw) at the time.
The world is a big place with lots of different people in it. I'm neighbors with a lesbian couple. I work across from a black dude and next to an Asian woman at my office. My boss is a white woman. All these people are the main characters in their own lives. As the tools to make art become more democratized, art will more faithfully reflect the world we live in. Just the way it is. I think panicking over it is silly.
