I do think they should actually downsize. Stop pushing out a new Assassins Creed every year or 2. Reduce the magnitude of the games a bit. First few Assassins Creeds were special. Far Cry games used to be great too. Now they just feel like a grindfest. As do the AC games.

But I don't think Ubisoft leadership would be capable of doing it right. They'd probably just lay off everyone who actually does work, and expect a similar amount of games.

There are industries where that works. In business software, that's incredibly common, in part because people buy the same software every year, or on a subscription. So the company makes a half decent product, hires an insane amount of people to market it while firing the vast majority of the developers, sells a ton of subscriptions, then coasts for a decade or two. Any time a competitor starts forming, buy them, lay off the staff, and coast on that too.

It's the business model of the vast majority of business to business software/service products out there.
