Let me put it another way, I feel that Nintendo lean too far towards protecting the children, at my expense. Sony and MS probably do too, but it's far more noticeable with the big 'N'.
At least on Steam I'm treated like an adult responsible enough to make my own purchasing decisions.
If Nintendo leans that far to protecting children, then why are there M rated demos to download on the eshop?
Why was it that most of the games I saw for Wii U's lineup involved shooting, stabbing, or physically hurting someone?
Nintendo is fine with adult material in games like violence, swearing, sex, drug use. Go play
Scarface on Wii to see what I'm talking about.
But censoring material about religion, racism, or homosexuality is not about protecting kids. It's about protecting Nintendo's image. Nintendo is meant to be played by everyone, and if they release games that attack or mock groups of people, then it contradicts that message.
