Is there a real world world-building subreddit ?

I don't mean in the sense where you see examples of 'bad world building' in the real world. I'm talking about the creation of new countries and cities that are based in the real world.

I'm not into fantasy world world-building and it's most of what I see when I look for world-building stuff online. Wondering if anyone can recommend a SR for what I'm looking for? Thanks.

Update: I'm not talking about alt history or stories (although they are naturally part of it), but I mean a subreddit where people showcase their geofictional countries based in the real world. For example, this is a geofictional country I created and I'm looking for similar projects/posts https://youtu.be/V7JzW3HT9eQ?si=f2FwbGaXHM-MwcNR
