Making a game is hard. Very hard. Designing a good game is even harder. FF XV game's designer decided to have characters like this, with this quantity and genders. Its his vision, and his/theirs vision should never be corrupted or the final work of art would be tainted and not replicate the original vision. If you like it, great, if not, move on. Appeasing to anyone else will just harm the game, so let them do what they do best, which is make games, whether they are good or not.
