That's been my thought too. All the big studios are competing for an incredible amount of money each game. Isn't there a decent formula for producing hi-fi rush games "cheaply"? How many people are needed?
If Google is addicted to reduction in personnel through automation, Microsoft is addicted to disposability. Almost all the work done on Microsoft-developed titles like Halo Infinite is performed by temporary workers who are employed for a period of months and then terminated. Microsoft thinks creative success is a commodity to be bought and sold, and it isn't.
I always end up having more fun with indie games (with some very rare AAA exceptions)
