Can I create my own sets?

Yes.

Moviestorm includes a complete set-building tool, the Set Workshop View. You can build indoor or outdoor sets from scratch, or you can modify any of the existing stock sets. There are over 60 stock sets currently available.

If you're a subscriber, you can also use the Modder's Workshop to import buildings and other items from Google Sketchup or build them yourself in another 3D tool.
