I would really like to see a tutorial or lecture about how to build concepts and how to "learn to learn." :3
A tutorial on how to think about creating functions for using in your games and how to write them with flexibility to run in many different games that may use the same function. (Template code tutorial)
Also, with ways to think about something and how to find out what it is that needs to be done.
How to write pseudocode or concepting for games so to make their construction smoother.
How to stack functions to make low level changes with a high level function. Writing functions in tiers. Making functions more portable and functional at high level.
Basically, a tutorial on how to think about making a game before you dive in and start coding.
