For a future subject, I'd be more interested in managing the actual code of any game. How does one correctly handle objects and structures, and the functions that control them? How to separate view from control and model efficiently with lite-c and what code samples are handy to use right away (for example, a linkedlist, hashmaps, garbage collectors...). Handling pointers, preventing memory losses, adding efficiency and optimisation are subjects where I'd like to have a broader view on.
Even trying making a correct division of your code over your files bring issues and nasty problems.
