This is the business model for most of the large gaming companies at this point.

Activision had three or four studios dedicated to Call of Duty leapfrogging each other to release one every year. (https://en.wikipedia.org/wiki/Call_of_Duty)

Their last (2022, pre-acquisition) annual reports literally spell that out.

> For example, in 2022, revenues associated with our three franchises—Call of Duty, Warcraft, and Candy Crush —collectively accounted for approximately 79% of our net revenues—and a significantly higher percentage of our operating income. We expect that a relatively limited number of popular franchises will continue to produce a disproportionately high percentage of our revenues and profits. - https://investor.activision.com/annual-reports
