I am not one to bow to canon in a gaming setting for canon's sake. The enjoyment of my players at the table is paramount, and gaming authors should expect me to fold, spindle, and mutilate their creations to accomodate my game.
That having been said, I didn't have to do a lot of that with this book. Sure, dates are slid around from one decade to another (in accomodation of abovementioned gaming fun) but the core of the book described the Spinward Marches well. There were even plot seeds dropped throughout that are still germinating in my head right now...
Altogether, a good, solid Traveller acquisition. I enjoyed reading this one.
