I have all that stuff downloaded. I also have Only War, along with Rogue Trader, which I eventually plan to make a duel campaign out of.
Welcome to the 40K RPG universe
I'm new to 40K RPG too and I just started a Rogue Trader campaign. My first purchases were the Core Rulebook and Into the Storm because it provides a good number of additional items, starships' hull and compoments. It also has the rules for alternate career, Xenos characters and expanded gameplay mechanics. While they may seem a little overwhelming to a beginner (I belong to such category as well ) there will be a moment when those contents will become very useful.
After those I bought: Lure of the Expanse, Soul Reaver, The Koronus Bestiary and Stars of Inequity.
The Koronus Bestiary is a must in my opinion, since it gives you a large amount of NPCs for your own adventures. It also features a Xenos generator if you want your Explorers to fight something no one has met before.
Stars of Inequity has a huge pontential but some parts of it are better suited for high level characters who are likely to be influent enough to venture into the farthest reaches of the
Expanse to found new colonies etc. However the treasure generator is perfect for awarding players after explorations. You don't knwo what artifact(s) the Explorers may acquire during their last exploration? Roll on the Treasure generator.
The System/Planet generator is also very interesting but I'd recommend to acquire a little familiarity with the game before trying more complex tasks.
Lure of the Expanse and Soul Reavers guide you through an adventure and they are not conceptually different from the other "scenario expansion". I have't read them yet, I just gave a look at some pages. Such kind of scenarios aid you in creating a very detailed story with ease. Just follow the book's steps
I have been told such encounters from those books are quite challanging for very low level character but I haven't started those scenarios yet.
I don't have Hostile Acquisitions,yet (I plan to buy it in the future) but if you like the rogue-style Rogue Trader it may be a good addition to your collection....
