I'm not a game dev, but I watch Tim Cain's[1] YouTube channel, and I think it's a treasure trove of experience-based stories and advice.

[1]: Tim Cain created the original Fallout (pretty much designed the whole universe), and a number of other successful games after. He's an engineer through and through, but wore a lot of different hats, and has an interesting perspective on all aspects of game dev.
