The Rogue Trader RPG was put out on the market by Fantasy Flight Games today.
It retails for $59.95
I can't say much more about it. Today is free RPG day so you can get some free pre-made characters.
I can see it is a different system than Dark Heresy, which is a plus by my count since it seems simpler. Dark Heresy was rich... and complicated. Cumbersome.
