Last year I purchased a pair of manuals for the role playing game Dark Heresy. Then I bought two more.
I have gotten together 4 different people interested in playing it. I have guided them through the process of character creation and an introductory adventure. Next friday, if the emperor wills it, my players and I will have our first official adventure together.
The crew so far is:
Redemptionist Cleric: raised up in a bunker in a warzone by religious fanatics. She likes burning things and new experiences
Malfian Nobleborn Adept: almost crazy and not really evil genius with a fear of dire wolves.
Naval Security officer: youngster who fought and killed his first space pirate when he was 17
Mech-Assassin: some lowly mechanicus worker who stumbled across a cult that tried to kill him, survived and killed the entire cult, then got promoted to mech-assassin.
