The author of the Lucas Empire history "Droidmaker", Michael Rubin, has generously put Chapter 18 of his book up as a free pdf download on his blog.
Lucasfilm didn't launch its Games Group (later Lucasarts Entertainment) until years after the Computer Division was underway -- so it doesn't enter the story until Act III (Chapter 18). To satisfy the curiosity of games historians, I'm also adding a FREE CHAPTER 18 here, for download, to give you a taste of that late chapter. This chapter chronicles the rise and supremacy of Atari, and the deal with Lucasfilm that created the Games Group and so on.Go get it here... after you look at the Sam & Max goodness (see below) on Telltale's site, that is!
Some things might not be perfectly clear, and some characters apparently not introduced, but hell, you're 280 pages into the book at this point, and you have to expect you've missed a few things. Still, I think it can be followed.
