I admit I haven't played a tabletop RPG before. Even though I own two RPG sourcebooks (one of which is Dark Heresy) and various free RPGs downloaded off the internet (not illegal copies, but RPGs distributed freely), I just don't have people to play with. The reason I got them is to read them. Sometimes, I find ideas I can use in real-life, if needed.
I hope to someday get a copy of the Rogue Trader sourcebook. Still, I would like to know something: Is it a good read for someone who is a fan of the material but most likely will not play it?
I'm quite happy with my purchase of Dark Heresy, so if someone is able to compare them, I'd appreciate it.
