Earlier quoted context omitted.
I’m just saying that if you count anyone who has ever played Candy Crush, your stats aren’t going to be particularly meaningful, and you’ll end up with a number like “three billion”. If the same number was cited for beer drinking, I’d be saying “sure, if you count anyone who’s ever had a Budweiser”, and it would be a valid criticism.
I get what you're saying. It would be interesting to see the statistics on how many people play non-casual videogames. And how many people drink craft beer. Though with videogames, it's still a meaningful statistic to include "casuals" considering it used to be taboo to play videogames at all as an adult.
There's a difference between a casual Candy Crush player and a casual Overwatch player though.
I wouldn't class the Candy Crush player as even a casual gamer.
