I just made a video the other day on a city in the Crater Edge called Los Fantasma (City of Ghost). From the city you can see about 6 Ghost Leviathens and watch them swim around in their "pack" (probably would be called a school). I have a weapon shop, coffee shop, bar/resturant, apartments, luxury condos, and ports (moonpools). I want to see about some good mods that give you more rooms and decore/furniture, but if I found any I would probably have to switch to PC gaming, which I plan to do anyways with Fallout and Minecraft.
