So instead of getting mad at the devs for making these abhorrent designs, you get mad at the people who have had the game ruined for them by association because of them.People who want to talk about the gameplay are not really free to do that when the discussion was shifted to talk just about those designs and nothing else. The same thing happened with Xenoblade 2.
But please, do tell what is acceptable to talk about or not, while giving moral lessons at the same time.
If someone is to blame for the derailing, it's the devs. Not the people who are disgusted by the sexy kids and can't look past them, which is the normal, understandable reaction.
