The mentality isn't problematic for me if it isn't manifested in some kind of "message" in the game. Yes, Ico depicts a boy helping a helpless girl, and in SotC the character is a male working to bring the girl back to life, and those reinforce certain gendered narratives that some people would like to see subverted. However, what is the sexist message of The Last Guardian? We know his thought process, but most who play it don't, so what is the "message" they will get from that game? They'll see a boy and an animal having an adventure. The mere presence of a male character instead of a female character doesn't send a sexist message, it doesn't make proclamations, it doesn't reinforce a gendered narrative. So for all the people who play the game without the knowledge of the creator's views of gender, what's the harm?
