I'm currently playing through Tales of Symphonia again and definitely noticed the lack of PoC, but on the flip side it seems to be telling its story about slavery and racism with much more depth and maturity than what FFXVI is (so far), which is crazy because Tales of Symphonia is a very jovial game overall.Well then maybe they should've said that instead of "We don't think that forcing diversity is good".
Also, the white main character taking hours to consider that "Wow, maybe slavery is bad, actually".
Tales of Symphonia lacked characters of color too (like most of the Tales of games until Arise) and did tackle slavery and racism ; it was the main theme of the story, even adding grey characters and sides. FF 16 team had to watch all of Game of Thrones (seriously).
