> First off let me get on my high horse and say the engineering in video gaming is generally more complex than the engineering I've done working in big tech. Yes. Having done everything from mainframe OS internals to proof of correctness to autonomous vehicles, video games are the most difficult. At the beginning, game dev looks easy, because the tools are good and modern hardware is very capable. But as you approach…
This is very interesting, what makes video game engineering so difficult?
An example - a 3d humanoid character. You need code to manage the mesh, the animation (probably skeletal), the animations themselves, all the blending logic, probably specialised code and data for facial animations, and then you need to make sure all of that can mesh with both input driven locomotion and AI driven locomotion - and that's just one problem domain.
And I'm grossly oversimplifying what's involved even in that particular area.
