Wow, I just now saw this as I was going through the thread. I think the only thing we don't have right now is the "open air spawn." You see, our spawn is a round dome with other domes off of it with hallways, but it's because it follows our theme.
Our theme is our Techno race. Robot humanoids. We wanted to go with geometric shapes to fit that, and our logo is mostly black and white, so our spawn is. People have told us they loved it and others have told us they weren't fond of it, so we're not sure what to do.
It's huge, by the way, so it's not like we can tear it down and start anew.
