Good stuff. I do like collecting gaming things - books, comics, figurines, etc. So once I'm done playing AC 3 I might pick this up. I just wont get it before in case there are spoilers.
It doesn't really have spoilers in the traditional sense of the game. You will see some characters and locations that you may have not seen in the game yet, but story-wise, there aren't really spoilers.
havent played the game yet waiting for the WiiU version and trying not to read much for spoilers.
