I have been reading "Slaying the Dragon: A Secret History of Dungeons & Dragons" by Ben Riggs which is about the TSR years at D&D. It's interesting as it covers the time when I first got into and was really active playing TTRPGs. It focusses on a lot of business details that I was unaware of at the time.

One thing I found surprising is how many talented writers and artists left TSR due to poor management decisions and an unwillingness to pay people what they were worth. For example, Tracy Hickman and Margaret Weis left TSR after writing the best selling Dragonlance Chronicles and Legends trilogies after not being given a relatively minor pay increase. Then the CEO threatened to sue them at a convention...

Anyways, it's an interesting read though perhaps not for everyone.
