I've built a couple of maps on the world builder (that was hidden away in the menus) and saved them as .Civ6Map files. I've scoured this forum trying to make sense of what we've got to work with but I'm still unsure what steps I'm missing. How do I play a game using these custom made maps? I don't see any way to select them when I attempt to create a new game. If someone could give me a step by step guide on how to make the custom built maps playable, or point me to a thread that already explains this, I'd be very grateful; thank you.
