This was something I started wondering about when I was reading a thread about Star Citizen, and about how space combat flight games were much less-common than they had been at one point, how fans of the genre were hungry for new entrants.
Looking at this list:

…there really were far more games in the genre being released in the late 1990s and early 2000s than there have been recently.
A similar sort of phenomenon occurred for World War II first-person shooters.

Back around the same time period, there was a glut of games in the genre, and they really have fallen off quite a bit.
Whether it’s a genre like these two, that hasn’t seen many new entrants recently, or a genre that just never grew as much as you’d like, what genre would you like to see more of?
Slay the spire? It’s a deck builder rouge like. Excellent game. Dunno if it’s what your looking for but I highly recommend it.
