I am interested in using Unity as a Level builder for Teachers in the area of Education. how hard would it be? I really do not want to the teacher to be faced with all the features of Unity. Just the basics: 1- Drag an object to the world from an Asset List. 2- Select a object or scene file and modifiy or change it. 3- Some kind of simple XML tree file that would save the environment. I imagine this can be done in a web player envirnment.
