A lecture that absolute beginners should not listen to People who don't know much but want to try making a one-person game -> It seems like you're just trying it out when you really don't know much. People who know the structure of Unreal to some extent and how it works will understand the explanation itself, but If you don't know anything at all, you'll just listen and think, "Oh, that's it." Don't expect detailed comments or explanations.
