1) Let's stick to video games for now, all right, :P? Honestly, just look at Super Mario Bros., pretty much the only other instance something like this has happened, it's phenomenonal, even now, like a quarter of a century later.
2) Honestly, if you're speaking of impact, Wii Sports pretty much turned the entire market around. It turned a console that was likely to sell 10m into a "you see, I was right, it only sold 100m LT, take that, Nintendo fanboy!" It most likely added more gamers to the market than the entire shooter genre. Also, please consider Sports Champions and Kinect Sports, high-profile attempts by competitors to try to save some market share for themselves. Move and Kinect would not have had a sports game as (one of) their killer apps had it not been for this monster right here.
3) I thought I might have on that one, xD. Could you please explain it then?
