I get what you're saying, the plurality of gamers want to play the new release AAA stuff. And the majority of movie goers want to see the latest Minions Emoji movie. And the majority of cheese eaters want to eat American cheese or at best Wisconsin cheddar.
These things are mass market slop which are engineered to be bland and predictable to make the most reliable returns for institutional investors. Discerning consumers know better and don't go by what's popular.
I don't think there is anything wrong with liking popular things and tbh this attitude that somehow you are better because you like more niche things is very close to snobbery. I am not saying that is your intention, but it can come off that way.
There are plenty of popular franchises that I've liked in the past. There are plenty of "slop" movies that I enjoy, I really like Mission Impossible movies, Fast and Furious movies. I've also liked some of the Call of Duty games. There is room for both.
