(re: The history of Sierra…) Ken,
out of curiosity I bought the book you suggested here. I’m now at the part which relates more to Sierra and to you and it has indeed some insights that make me keep reading and turning pages. For sure it adds a lot the fact that from a distance, this involves part of my own life, as a kid and young person, when I was looking foreward to play the next Sierra adventure… and still find now many of them amazing.
Nice suggestion, thank you,
