There will always be exceptions to any trends, but I wouldn't say the deluge of generic roguelike platformers with 16 bit art has been paticularly flattering to the indie industry. Have things really progressed in 2024 since 2012 in the same way that 2012 was abjectly different from 2002? Not really, you could release Slay the Spire in 2012 or 2024 and it wouldn't look out of place.
They mostly seem interested in JRPG anime slop, and even then Expedition 33 was released just this year and is probably the best example of that genre from the last 20 years? That's also by a relatively small studio though..
I would agree that big AAA studios are basically entirely creatively bankrupt at this point, but that's not exclusive to games, the same trend is apparent with movies (remakes of Disney movies, Star Wars sequels, etc.).
Slay the Spire was released in 2017. Are you accounting for indie games?
