On “What direction and resources? Advice from the pros.”

Here are my fav videos. bobby Anguelov He also has a great chat about animation systems and ai. Check out his engine on GitHub great code to read. A Industry veteran. I am in love with the decima engine..I don't know why. I just love it Here is a great talk from their engine tooling team. decima engine tooling Inspired me to consider immediate GUI for my engine using nodes. Many systems are going this way..procedural generation, scripting, shaders, rendering architecture division 2 engine There used to be one from Frostbite team but it's no longer on YouTube. These are ones I return to on a regular just to inspire me.

On “Is there a good writeup on composition based architecture (components but not ECS)?”

Video, not a blog post, but it's exactly what you're looking for (and is modern): link to this video It goes a little deep, but Bobby did post source on his github eventually so you can look at it if you want some kind of grounding.
