I think that diversity by color is good because it often brings with you diverse ideas. Having the same group of people over and over in companies, movies, games, etc. leads to stale ideas.
I loved playing the Battlefield 1 intro because of the story of the Harlem Hellfighters. It was something new and different. The same with the last story mission. Diversity of characters can lead to new, interesting ideas.
Seeing generic white protagonist #304 on game covers gets old quickly. Gaming can do better. I'm glad EA realized this.
