You may have seen some comments from a GameSpot interview by one of Final Fantasy XV‘s directors, Hajime Tabata:
“Speaking honestly, an all-male party feels almost more approachable for players. Even the presence of one female in the group will change their behavior, so that they’ll act differently. So to give the most natural feeling, to make them feel sincere and honest, having them all the same gender made sense in that way,” Tabata said. The game certainly doesn’t shy away from the theme of male intimacy, with the party sharing a tent, protecting each other in battles, and holding no qualms about showing open concern for one another.
For Tabata, the journey will have the cast adopting what he dubs a “boys will be boys” type demeanor. “It was the story we wanted to tell and what we wanted to show players,” he explained.
“The world might be ready to see the curtain lifted on what boys do when girls aren’t around, when they come out of the tent all prim and proper. That’s kind of the idea behind it… we think, male or female player, that everyone will feel a certain connection and bond with the four characters.”
