Most people who say this mean "this is what AAA video games are". Rocket League is arguably not AAA but is clearly taking its more recent changes from it.

As you say, many new things are being created, and the solution for the most part is simple: Don't buy AAA. It has almost no appeal to me anymore, and even when I hear about some franchise I like or used to like, I just assume the worst if it's making the leap to AAA, and to be honest, that metric hasn't failed me in a while.

I'm late to the bandwagon and just bought Slay the Spire for $10. No microtransactions, no unlocks, no AAA garbage at all. Just money for fun. That's the solution. Don't play games that are just platforms to deliver psychological manipulation to extract money from you when there are games that will deliver the same basic dopamine hits for defined amounts of money, and for goodness' sake, don't pay money for things that are just platforms to psychologically manipulate you into giving them money. And often, frankly, aren't as good at the dopamine hits anyhow since they have to wrap them around manipulation.
