I think we can all agree this is some straight bullshit.
I don't think women or girls really care about color of controllers. If they do.. why not offer some pink or baby blue controllers, you fucking shitlords?
Now. The shape, which is briefly mentioned later in this article, is a factor.
Before analogue sticks, in the NES days, you could just have a block. To ensure control of analogue sticks, you need to have wingy-things. Personally, as a man slightly taller than Osama, the Xbox 360 controller works alright at best for me. Cramped, but fine.
Google's alternative looks like it might work for women and children who aren't fat better, which I think makes a lot of sense, but is less good for adult men.
Why aren't these companies working to offer interchangable/adjustable lower wings on their controllers?
