I think there's a simple solution here. If you're an adult, stop playing games targeted at kids, if you're going to get upset about it. That means stuff like Splatoon, Mario, and Pokemon, is simply not for you. If you're going to force your way into this audience, when these games are not made for you, then don't get upset that Nintendo isn't catering to you manbabies. You take what you get, and you like it as it is.
Options? OPTIONS? No, I don't think so. There is no such thing as options. Even Jesus didn't get an option when he was nailed to the cross. They build the game how they please. If you want voice chat in Splatoon, you better hope Nintendo makes a similar game for their adult demographic, because they don't owe you options. This game wasn't made for you, okay? It was made for the kids. Everyone is always asking someone to think of the children. Well, Nintendo did just that.
Stop hating on them. Instead, appreciate that they're looking after the most vulnerable of our society. These kids are the future gamers. By the time they start using voice chat when they're older, they'll be more sensible and mature than the average gamer is today, because they won't have been exposed to the filth you get online. You have to think about the long-term. Nintendo is nurturing the future of our hobby. They deserve to be applauded for that.
Fucking IGN. Always stirring shit.
