I personally don't care about the character design.You say "these things are normal in Japan", or "we used to argue about it a lot, but now we've gotten used to it". Perhaps American developers have noticed this and believe it's possible to normalize it as well, wanting to include people like that in their games because there are people like that in America? Both cultures feel distant to me in this regard, but maybe we just need to accept them as they are? Or if we are going to criticize, shouldn't we criticize both?
If the game is good then I'm good.
