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?
