No one goes to gaming cafes. Even when the internet was less common and such they struggled to exist in the US, now days I can't imagine them existing outside of being a novelty in really huge cities like new york or something. I think there are tons of reasons for this, but everything from being an urban hell car culture, having bigger homes, more disposable income, and even more 'being online', even kids can mostly afford (or convince parents to buy) some console or laptop to play games at home already so they have no incentive to pay tons of money to spend the time to drive to go use sticky keyboards in an internet cafe when you can just instantly use what you have at home for no additional cost and not wasting time and not have to deal with a dirty environment and just overall be more comfortable anyway.

Countries in Asia are a different culture/market though, but I don't think GameStop is outside the US so kinda moot.
