Heres how that works:

Gaming got popular.

Normies like fancy graphics, production value, and are swayed by fake trailers and mass marketing campaigns.

(Doing all that well, in a way that people can actually afford to pay for, is extremely difficult and very expensive)

Corpos discovered they could turn everything into primarily a market for subscriptions and micro transactions, that houses a game, and most normies kept paying for all that untill the economy entered the Second Great Depression.

... its basically Dutch Disease, but for video gaming.
