Please provide evidence, also including as to how many only hated it because of the character's skin colour without any constructive criticism. I'd also like to add that of course there's dumb&*$# reviewers who say statements like that for a click, but what I'm countering is the two of your implications that racism is what bogged down the game's reception. A bad apple does not make the whole batch bad, amirite? Goes for reviewers. Finally, I don't buy the political elephant in the room, which is the WASP 'victimisation' narrative that our discussion now is flirting with but not getting into (which is good, because I do not want to get into it).
I'm on android, see my sig, look it up yourself on google. Plenty of evidence before and after the games release.
Everything in the above reply is my opinion, from my own perspective and not representative of reality outside of my own head!
-Android user, please be gentle with critique on my spelling.
