I got my eagerly anticipated GM Kit from Barnes and Noble's today...and was extremely disappointed. I mean really...all it is, is a rehash of the DH GM Screen with a few more weapons and the Base crew ratings. It doesn't even have the Ship Combat actions on it. Oh, its good some neat (if not regurgitated) art on it. The thin pamphlet that came with it has 4 pages of actual GM info, which are a few hastily thrown together charts. The other 23 pages are another adventure....whuppity.
Im usually very happy with FFG, but it seems like they have really been cutting corners on the RT stuff. The GM Kit definitely is not what I thought it would be. If you have a DH screen, I suggest you just use that and save your $20, unless you really need a new adventure.
Only the Emperor knows! Did they correct it in the Drydock supplement? No! For 25 years I´m a player and GM but I´ve never seen a GM screen that really contained the things you need for running a game smoothly. So what to do about the Extended Actions table? Copy it an add the default difficulty and don´t wait for a GM screen to be published! The booklet that usually comes with the screen is usually worth waiting for. But according to the comments I read so far it´s not THAT good. Nevertheless most of the time the booklet is good for some adventure ideas and another bit of atmosphere which I really like in my games.
