I mean, to me those examples feel a little unfair. It's easier to be groundbreaking in a nascent medium, and those came out thirty years ago - way before the term AAA was even used in the games industry. The bar for interesting and groundbreaking can't be "literally invent a new genre à la Wolfenstein 3D". That's a little bit like saying "I feel like the blockbuster movie climate is so stagnant these days. When was the last time someone did something groundbreaking like The Jazz Singer?"
For my money what Remedy is doing with both their mixed media, their connected universe and their storytelling is pushing the boundaries of AAA gaming, but if that is not enough for you then how about Half-Life: Alyx (2020)?
For the record, I do agree that the overall AAA landscape has become stagnant and risk-averse, much like blockbuster movies. But it's also unfair to say literally nothing interesting is happening.
