I think this. In the recent slew of screenshots, there's actually a Black and Asian member of Kingsglaive.
I've mentioned that, sure, there ARE more White characters, but with these three, there's already some sort of cultural diversity existing in FFXV's world(more so if had the world been completely Asian/Anime-like). I just say, I HOPE this kind of diversity carries over into the game itself. I want to see some Black NPCs walking around, EXISTING in the world. Hell, something more than White or Japanese Asian, especially considering there's a lot of Malaysian programmers working on the title.
