I'm not saying that it's not irresponsible to grow to the size that they have, but I don't think people understand the staggering difference in the size of the development teams between GTA and Hollow Knight.

MobyGames lists 4,771 people in the credits for GTA V and just 85 for Hollow Knight. Honestly most of those on Hollow Knight are translators and testers, people who weren't working the full length of development time.

As a reminder, 99.9% of the cost of a game is number of staff * salary * time.
