On one property I used the castle models and even changed one of them so that the doors were open. On another property I build a barn and house. Then another I used the starbase models. There was also one property where I build some of the creator modular buildings having to change them because the parts were not available. I know on a few of them I added some automation – like a cannon blowing up a wall 🙂 I think I was working on a cave/mountain scene when it shut down.
