To be fair, some of that 8 million might play games using a controller, since that might be what they prefer.
More and more, I think we need to drop the "made for console" and use the more accurate term, which is "Made for controller" or "Graphics not optimized for Custom PC". The Xbox One and PS4 are no different then a Steam Box or low end PC now a days.
I know that maybe you mean well, but when was the last time you bought a console that had a mouse, and key board ?
or when was the last time you bought a computer that came with a hand held controler ?
People who use computers spend a lot of extra money to have state of the art, or as near as they can afford state of the art systems, and go to great expense to enjoy there games with the best graphics, and fun factor they can make for them selve's with a mouse, and Key Board, which is what they should expect.
I do not like controlers, I do have a PS3 which gathers dust most of the time, I doubt I will buy a PS4 ( Ever ) and you could not run fast enough to give me one of the new invasive XBox systems.
Yes I do have a controler, I use it for Console emulation on my PC where I expect to use a hand held controler, but I do not expect to use a hand held controler for a PC game.
I guess you mean, everyone should take there PC, and change it out for a Console, why spend any extra for better, let us all drive a Volkswagen. (Peoples Car) Everyone should have the same.
