If I'm rattling down a list of my favorite games ever, they're heavily concentrated in the last decade, with a couple of stragglers from the decade before that. I don't think that's recency bias; I think developers have just, in general, gotten better at honing in on what people like, especially in the age of rapid patching. There's plenty of negative that comes along with this too, but for every game like Diablo IV that patches out builds because they were too much fun and impacted their live service retention rate, there are plenty of games coming out of early access after learning what worked and didn't work with their players, much more rapidly than the old days of iterating on yearly sequels.
