This idea may be better for creating the best tutorial video or something once the dungeon editor comes out...
but could there maybe be a prize or something for the highest rated/viewed tutorial video?

I've heard there's going to be lua scripting, and that might scare some people

Are you suggesting a tutorial video for the modding tools? Not the game its self?

Making a tutorial video to teach people lua, would essentially be instructing a course on how to code.
