As I reported, I could have misremembered, which I did (I remember valve did some research on it). We were discussing if it was reasonable to make split screen games and it was brought up multi keyboard input, I reported controller should be used, hence the stat. Steam just proved that at least 48M people have controllers on PC, that is a lot of controllers! As for non platform users, we literally have no information on them and no way to gather such information, so for the purpose of this discussion, they don't exist. Being an edgecase cuts both ways (yes, steam is that big) I'm not sure if you read anything between the lines, I remember it was 50% of steam player have a controller, I remember wrong and it's 33%, that's about all I have to say on the stats. I would not recommend using a keyboard for split screen gameplay, we have a better alternative, especially with the loss of mouse. From my personal perspective, the keyboard is always a poorly optimized gaming peripherals, it's the mouse that makes a difference. The keyboard is useful when jumping into chat, but that's about it. For a while there were those poor quality gaming boards, made more sense than a keyboard and had an analog stick included, these disappeared from the market sadly, but made more sense
