Certainly following all those videos is an inefficient way to learn. As smoyer said, it's more about the craft of coding, so maybe I made an apples/oranges comparison.
Does anyone know about the depth and structure of the code in "How to Make an RPG"? From the post, it looks like it is focusing specifically on gameplay issues. Handmade Hero is covering quite a range of topics from basic gamepad input and audio output (done early in the series) on up. It is structured so that it's relatively easy to port to non-Windows OS's, and I like the live-coding feature which really shortens the code-compile-test cycle.
I guess it would be nice to see the table of contents and maybe a sample chapter or excerpts.
Yea... Handmade Hero is a very awesome idea, but I can't imagine the amount of dedication it would take for someone to sit down one day and decide to watch all 300+ videos. It's like an order of magnitude more content than a college course already and it's clearly far from finished.
