There's a very long but interesting Twitter thread from an ex-Square Enix producer where he talks about how companies arrive at sales targets for games, how discrete AAA games are fighting a losing war for gamers' attention against live service games and why the price of AAA games will (and has to) go up from the publisher's perspective.
Again, it's long but I do recommend that people go through it. For example, near the beginning he gives rough numbers about why a game needs to sell some silly number like 8 million copies at full price to be considered worth making. It gives some perspective on what is currently going on in the industry.
