(Note: This course will never be deeply discounted: it is not part of Udemy's "kamikaze marketing." If it were, I'd have priced it three or even four times higher.)
This is a class about how to design episodes for games (both video and tabletop) - call it level design or adventure design - rather than how to program them. (Level design is a subset of game design.) There is no instruction in using specific software, for example, but a lot about what to put in the level (and not put in it). Adventures (for D&D) preceded video game levels, and levels follow the same principles as those adventures.
In games that require episodes (stages, missions, levels, adventures), the episode designer is the person who delivers the enjoyment to the players.
Entire books have been written about level design, though much of the material in these books describes how to manipulate a specific level editor such as Unreal III. There's not so much in these books about the actual design of levels/adventures. This course is strictly about design, not production, though we do discuss documentation.
Udemy says the course is 8 hours. It's actually half that, they count as four hours the file I supply that contains all the slides used in the videos.
