I thought a slide with examples of use cases for these three concepts would be a nice way to round out the introduction. Giving them real world applications that we’ve all probably seen/played before would help cement the concepts in our brains. Personally I retain information better when I know the when to not just the how to. As long as I know when to use a concept the how is usually easy.
To go all out, perhaps it’s even a separate, short video with some footage from games and a PDF cheat sheet PDF to refer back to!
