Most data suggests that the average video gamer is roughly 30 years old. Which if you think about it makes sense. I'm 35 and I grew up with Nintendo, Sega, etc. Kids today have so much more to occupy them.
I've been teaching for 15 years and each year less and less kids talk about video games. Years ago when a new game or system came out I would have 15-20 kids out of 120 staying home to play. Now it's about 2-3.
As for sports games. Hardly anyone even talk about them. Maybe Fifa and NBA. Once in awhile Madden.
