Same thing with my music industry analogy too. There are so many choices to choose from that specific niche genres or bands only fills the void. I also replay older music and bands too because they never get old. Pop punk music for example didn't died out because they weren't as popular back in the 2000s. I still encounter alot of new and upcoming bands that I found on Youtube and Spotify.

Indie games fills the void that some people are looking for if they feel that AAA isn't providing them enough content.
