Break down what the qualifications of a casual gamer are. People who usually put hundreds of hours into very simple, very repetitive tasks with the exact same payoff each time, only to take shear pleasure in restarting a few hours later to do the exact same thing. People who maybe play two games total on an annual basis.
I see it every. single. day. Tons of kids, and adults alike coming in with stacks of the same two games: Call of Duty, and Madden. Or Call of Duty and NBA 2K. Or Halo and NHL. Nothing else is in their library. And I sometimes ask why they're trading them in. I get the same answers. This is all they play, and a new one is coming out. Or, even worse, this is all they've ever played and they're giving up on gaming. I get the impression they've only ever thought this was all there was to gaming without ever branching out.
These people call themselves 'hardcore gamers', something which without our even knowing, they took from us, and even worse we don't even remember exactly when that happened. And the more we each individually try to figure that out, the answers become both clear, painful, and even further each time. We made gaming successful by supporting it. They made gaming mainstream by making it just like Hollywood. We keep playing because the popularity has made it look better, like we always wanted, but the cost has been the soul of real gaming.
Does that make us all casual gamers now?
NO.
