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?
Depends where you’re starting. If it’s sticks and stones, yeah, you’re going to spend a lot of time building up. Even getting to the prerequisites for the Gingery-esque machine shop will be a trick, and you definitely need machining first.
Sam Zeloof is the guy that actually did the semiconductors bit. He makes a transistor in the linked video series starting with a commercial wafer, some basic chemicals, a spinning piece of tape and an electric furnace. I read papers and just Wikipedia to get ideas for the parts he doesn’t cover. The standard ways of doing things are heavily constrained by scalability, which as an artisan you don’t care about, but will breeze past other things you really do, like ability to work in a small space. And, if you’re starting from scratch, using only common, locally available elements.
