Is there anything you're into that no one or basically nobody is into?

There's an Aztec city building game called Tlatoani. It's in early access, but has enough meat on the bone that it's one of my goto games.

Out of curiosity I checked Steam DB for active player numbers. I have discovered at any given point I am 10% to 25% of the given player base BY MYSELF. I am 1 of 4 people playing this game right now in the world. With the prevalence of the internet I always assume whatever weird bullshit you're into there's at least a thousand people talking about it; making memes outsiders could never comprehend. It's actually novel to fly under the radar for once.

What do you do that doesn't have a community associated with it?
