My only issue with the series is that he uses WinAPI instead of something more... sane, like SDL or OpenGL; which makes the code much more obscure and low level, and the code not portable at all.
I guess, however, that I could learn a thing or two about getting stuff done and structuring an engine/game. Wish I had the time to watch this.
Actually I found that to be one of the major strength, it encouraged me to look into how the corresponding Linux API's work and made me realize that it isn't all that hard to get something like an OpenGL window (at least if you use GLEW) with basic input working. Even something like the dynamic code reloading he does by using Windows API calls, can be ported fairly trivially to Linux.
