I own All of the books, Rogue Trader as a setting is Amazing the issue is the Mechanics do not match up to the scope. I have read Only War, it is pretty awesome depending on your regiment you can have both genders. Typically the Munitorium keeps Regiments as one gender to ease complications but the expanded universe tells stories of mixed gender regiments as well. The mechanics are sound and if you want to tell a story similar to Saving Private Ryan, or a longterm game where you are shuffling from battlefield to battlefield than that is the game for you. I think what helps hold it together and promote an excellent environment is the Regiment Creation rules which if we are to run a game via forum will help with group cohesion.<br/><br/>As far as power level is concerned the Players begin slightly above Dark Heresy level except for the fact that everyone is well equipped, hell if you are a siege team you can start with a rocket launcher. My only suggestion is to have each player create multiple characters so if their character get's fragged they have a backup character that can jump right into the action.<br/><br/>If people have interest I would not mind running a campaign of only War.<br/><br/>~ RR
