I'll try the line of apartment idea. May have already done that but I'm not certain. Think I'll also just try tearing down and relocating buildings that are in the way and rebuild them elsewhere to make room for more housing. Maybe I'm not doing that enough.
It would be cool if they added a high speed futuristic train that could be built both above and underground. And make it so it could be built through some of the large holes made by the worms (not the ones the worms are actively using of course). But I think it would look really cool to see sections of the train through the holes passing through in a tube. Something like this--> Future Train.
Cool, maybe I'll pick up a Dune book. I've been looking for something new to read.
