Shigesato Itoi (Creator of the Mother series) on Gay People.
Itoi: "Well, for example, there’s a gay person in MOTHER 2. A really passionate friend who lives in an England-like place. I designed him to be a gay child. In a normal, real-life society, there are gay children, and I have many gay friends as well. So I thought it would be nice to add one in the game, too."
