I've skimmed the relevant portions of the book, and while I really like the idea of a chaos raider based campaign, details on how to build/acquire/maintain a ship are lacking. Could you use Infamy score and then just match it up with the Profit Factor rules found in Rogue Trader? I would assume that the rest of the ship rules would remain the same (ship stats, systems and tactics etc). I'm not sure that you'd need a navigator either, since the rules appear to allow a sorcerer to learn warp navigation.
thoughts? suggestions? comments?
