Well, a lot of it is the same as in the Construction Sets of Morrowind and Oblivion, so experienced modders wont feel out of their depth.
For new modders, they've also got some online support. (As will we).

- Scene Editor: For editting the complex interactions between characters.
- Dialogue Views:
- Dynamic, Real Time Shadows -> for object placement (something that was a lot harder to view and find in previous games).
