The tutorial is the wiki. I used to play Dwarf Fortress back in the 2008-2009 era, and I kept going back to the wiki when I needed to learn something. It was, and still is, comprehensive, containing not just a "getting started for beginners" tutorial page, but also a list of every building and workflow (from ore to metal to swords and armor, from seeds to plants to food and drink...). In-game tutorials are not the only way to learn about a game; a well-maintained wiki (that isn't on wikia, oops sorry they're called fandom dot com there days — but that's a whole other rant) is also an excellent resource. And certain types of games seem to lend themselves to having well-maintained wikis: Dwarf Fortress's wiki is perhaps the best I've ever seen, narrowly beating Minecraft's also-excellent wiki.
