OK! I tried running it out. I went west because, well, I always go west.
Fun, but very, very long. A thing that should be done with others. Also, maybe bring supplies you can lose, because bringing nothing was just a bad idea. Bring food, a stack of dirt and a stone sword, at minimum. A bed too. Naked Caveman is great if you're set on a plot, but not so great on the run.
Lots of great stuff right out at the edge of 9K. A beautiful birch forest right on the sea, but also another area a tad north with loads of cliffs straight up around a bay. The cliffs are the best I've seen and we haven't really done that before, but I could see us settling either.
Also, we have more to go.
