I asked for the Lucasarts history book for Christmas. My family and loved ones betrayed me, and bought me underpants and video games instead. Oh well. Now I can read some for free!
Gamasutra have a chapter of the book up, and while it involves neither Guybrush Threepwood, Purple Tentacle or Grand Admiral Thrawn, it's still interesting. It's about Habitat, put out while they were still called Lucasfilm Games, a pioneering online game for the C64 that you've never heard of but will love reading about.
