Getting my group together, one character for each RT class actually, Im looking at the Two Adventure campaigns published.

The three stories in the Lure of the Expanse
Or the Warpstorm Triology where Frozen Reaches starts it all.

Any suggestion to what campaign I should choose, and why - whats good about them, and what is the bad part?

I am in the same boat really and was thinking along the same lines. Would also like to see what folks think of them.

Also, having one of each class, good for you. Nice sized group, should be fun.

The question you should ask yourselves is: What concept do you prefer?

An exploration, a long voyage in unknown reaches? Then go for Lure of the Expanse.

Or would you rather prefer a more political gameplay with a tense, consistent concept? Then go for Frozen Reaches.

Having played none of those adventures, I think I would prefer Frozen Reaches by far as I love this Seven-Samurai-Theme. In my opinion, this concept seems to be quite more consistent than "just another voyage-adventure".

Either concept would do, but my group would love to have loads of roleplaying oppertunities - so the concept would be, the most mature story, and the story with the most depth to it.

Frozen Reaches then. Lure has the NPCs interacting with a wide variety of NPCs, from the 8 other Rogue Traders to the Priest-Kings of Vaporious, I found there was less depth to the campaign. I'd suggest running it though, as it can take a good 15-20 sessions and that could be long enough for the next Warpstorm adventure to be out.

I don't have Lure of the Expanse , but I've heard good things about it. I do have Frozen Reaches , and I really like it. Of course, I'm converting it to a Dark Heresy (Imperial Guard) adventure, so my play through will be quite different from the norm. Read the blurb on each, pick the one that sounds like it will fit your group best. From what I can tell, you can't go wrong with the Rogue Trader adventures so far. DH is a little more hit and miss.

I finally found some good reviews on both adventurers - and to be quite frank - they sounded like something on the bottom of the mediocre range - this is the reason why i did not preordered more FFG adventures after the ones from Dark heresy.

Its even to extreme cliche for the 40k universe... Looks like Im gonna design an campaign for tomorrow then instead of picking up those adventurers.
