How can I export the whole of Atlas Park as something I can use in Unity?

[Gabbos]

I want to pull out all of Atlas Park and get it in Unity. I'll be honest and say that I'm not very savvy in this area, so I'm not really sure how to proceed.

 

Most of the pigg viewers that I find don't seem to work very well.

 

But even if they did the game seems to save cities as .geo files and I'm not sure what to do with those or how to make them get alone  with Unity.

 

Any ideas?
