Well, in Star Wars' case they do. This book will now become canon. So the events they say happened in KOTOR will also be canon. I mean, I guess you can ignore canon, but that's like saying "I don't like that Vader is Luke's father I'll pretend that didn't happen."

They've decided that Revan was male, but you still have the option to choose the gender of Revan when playing the game. And I bet that if they made KotOR III, you would still have that option.

Same thing for light/dark endings.
