The Rogue Trader book from Fantasy Flight Games is a great introduction to the game system. It starts with the sample characters (which is kind of odd) and continues on to explain the characters, combat, skill check rules and general game system. I was quite impressed with the thorough treatment of the rules in such a short span of time.
The latter half of the book was filled with a great mini-adventure that was entirely non-linear. The players actually have choices in the flow of the game. I really enjoyed reading the book and the adventure. I think I would also enjoy the game system as well. It seems to be a good mix of technology and mysticism. I doubt I could get my current group to play the game, though. It’s just too dark for their tastes.
Grade: A — Great descriptions of the system, characters, combat flow and the adventure made for a top-notch introduction to the Warhammer 40k RPG system.
