When ever I got to a midnight launch or even an E3 type event, the make up of the gamers I see there is usually quite diverse.
The above is New York City (Central Park).
The Pokemon Go crowds were very diverse. And then you have the Asian markets too (Japan and South Korea in particular being gaming hotbeds). Are a lot of gamers white? Sure. But a lot aren't.
I mean gaming is simply a fairly diverse hobby. Actually I think it's cool that gaming can bring people together like this.
