It&#x27;s not exactly 200 hours as Casey regularly goes well into the Q&amp;A session and adds things past the first hour. But that&#x27;s not really the point the OP was making, I guess. I really enjoy watching HH and I have nothing but respect for Casey and the way he&#x27;s doing these videos, but you can&#x27;t possibly maintain that the code he&#x27;s writing should be taken as an example by anyone.<p>The HH code is just plain bad, dangerous, unnecessarily &#x27;optimized&#x27; (read: taking ugly shortcuts or incomplete simplifications) in places where it doesn&#x27;t matter, while super-inefficient in places where it <i>does</i>, it&#x27;s untested, full of TODO&#x27;s, does not use any modern language&#x2F;compile features, it&#x27;s basically just a lot of lines of code thrown together with minimal design (I do like his seperation between the platform layer and the game layer though). I&#x27;ve watched and enjoyed over 100 hours of HH, and the process the game is going through is very interesting, but in terms of code quality and suitability to &#x27;learn game programming&#x27; I would not recommend it.
