I don't think I could learn that from deconstructing Cyseal. When it comes to importing sounds and writing script i am sure they will be making videos on those shortly. IMHO they really didn't need videos on the terrain tools and placing items its pretty much self explanatory when you hover over them and if they are planning on doing videos on all of the simple things in the editor first, we could be in for a long wait on the more complicated side of things (unless someone else figures it out and posts a tutorial)
