I spent some time playing around with the Donjon world generators.
After a lot of attempts, I ended up with this world using the SciFi World Generator (somehow the Fantasy World Generator and Fractal World Generator just didn’t seem to make anything I liked for potential regions to place the Vikings, Mayans, and Dinosuars).
Specifically, I needed enough land near the tropics as well as near the sub-arctic regions. Wanted an interesting coastline with lots of bays and water passages.
I am not really an artist or a mapper, but I’ll see what I can do with this.
