I have just finished my first read of the Rogue Trader rulebook and have the feeling something is missing.
After testing the ship creation system I have come to the conclusion that the Spaceship material is thin. I really hope FFG will release soon the Spaceship Handbook of the quality of the Inquisitor's Handbook to add more material cause right now it feels stale. I just fear that the oversimplified template (example: only 1 battery per side for all but Lunar-Class Cruisers) limits the development of new stuff.
This kind of simplified mechanics are appropriate in Battlefleet Gothic or Epic 40k where each players controls fleets/armies, but in Rogue Trader it would have been nice to have detailed ships when the players control one or very few ships.
Sure the rulebook say to watch out for more (What about the torpedoes?), but even those would take up only a corner of a page ...
Anyways if somebody knows of anything in the pipeline it would be cool to know.
