Why do you find that insulting?  If a couple has a kid(s), they would want their children to do the same.

Statement posted on Nintendo's official website:

"We apologize for disappointing many people by failing to include same-sex relationships in Tomodachi Life. Unfortunately, it is not possible for us to change this game’s design, and such a significant development change can’t be accomplished with a post-ship patch. At Nintendo, dedication has always meant going beyond the games to promote a sense of community, and to share a spirit of fun and joy. We are committed to advancing our longtime company values of fun and entertainment for everyone. We pledge that if we create a next installment in the Tomodachi series, we will strive to design a game-play experience from the ground up that is more inclusive, and better represents all players. "

That would imply that by playing a life sim, one can change his sexual orientation, which is ridiculous. I don't think there is any study that can support this. 

That's all they had to say.

Sigh. Once again somebody failing to grasp a simple concept. A gay movie store is so called because it stocks gay movies. If it stocked straight pornos, it would just be an adult movie store. They specialise so that there is no confusion and save the blushes of any people who may get confused. Nobody is "yelling" or "screaming" about rights. To put it as simply as possible, in a life simulator, it would be nice to be able to simulate our own lives in this cute fantasy world that Nintendo has created. And without that option, there seems little reason to play it. And you say "only" 7/8%? Out of 7 billion people, that's a hell of a lot of people. 

Great response. Even if nothing happens, they address the problem, which is that they can't just patch something like that in (as many, myself included  thought they could). Whether it's PR bs or not, I still see it as a positive reaction. 

What a silly thing to say. The gays just want to treated and represented fairly and equally. 

This game isn't the Sims guys....you don't really control any of the characters and it is obviously for a different target audience. This game is just supposed to be ridiculous and silly, not make any social commentary...If you don't like the fact that there are no homosexual relationships in the game, don't buy the game. You are entitled to your opinions, but the amount of outrage over this is absolutely ridiculous...

Also...your over-generalization of anime is pretty ridiculous. I get hyperbole but usually it is supposed to have some basis in reality....that is beside the point though...

I'd also like to point out I'm not getting my knickers in a twist over this. I'm just disappointed as I was looking forward to it and creating a little virtual world for myself and the people I love. I didn't even think about this before the news because, as naive as I am, I forgot that these things are still left out. Because sometimes I forget and think we live in a world where people are able to have freedom and inclusion in everything as long as their actions don't hurt or endanger anybody else.

Also, to the straight people here who are complaining about gay people asking to be included, if it has nothing to do with you and nobody is trying to spoil it for you, why do you even feel the need to speak up? It's because of the persistence of the "us and them" culture that goes on. It's really sad. All of my friends bar one, both male and female are all straight. And when it feels like a "we" and not a "us and them" it feels amazing. I must just be blessed to have such awesome friends huh?

That may very well be true, but a parent (some parents) want the best for their kids.  And even though that might not change his or her sexual orientation, a straight parent is going to damn sure try.  That's just being a parent.
