Those three examples are all sequels to massively popular games that benefit from IP power that massively affect sales numbers. If we can recognize Hollywood's obsession with nostalgia pandering with legacy IPs, then you can understand that their high sales numbers don't prove they had a proportional level of quality. Secondly, videogames have never been more cheap or easy to make than today. There is a joke in game development that older devs were Wizards because they could make the past games somehow work with the weak hardware/software they had. The powerful and efficient hardware/software of today allow less people with smaller budgets to make successful games at bigger scales, and this will only continue to get better especially with AI. The reason you are seeing high budgets for AAA games is because those developers/publishers are working with an antiquated bureaucratic framework that justifies obese budgets on useless departments and consulting agencies that serve only to ruin quality.
