Mine's starts out as a trench kinda like the boys starter base second picture and then I sorta expand into an underground empire with man-made tunnels and rooms. I can dig tunnels awesome but my building skills above ground are kind of mid. I'm a girl BTW but my friend who is a girl builds a stone tower and just enlarges it as the game goes on, I also have a guy-friend who builds starter bases without roofs and he gets attacked by spiders all the time which is kinda funny LOL!
