I am willing to bet that 75%+ people in high school still play pokemon but just don't publicize it. Back when I was in HS, I knew a lot of people that still hoped on it for nostalgia feels, and during senior year, everyone just started making it public. For me, senior year was a year where judgement was let go, it was the final year of grade school so everyone was just out to enjoy themselves and didn't care about stupid labels.
I take my 3DS with me to college, and thanks to streetpass, I can see what people are playing. Like 45% of my streetpass people were pokemon Black/White(2).
That's my experience anyhow.
in any case...
enjoy ~
