I did a quick search and couldn't find a similar thread, so I'm going to start it!
I hear a lot of nonspecific talk about RPGs around here, but I've yet to hear anyone actually go into any detail. If you want to do so, here is a thread for that. Crazy stories, talking about setting ideas, just talking about the latest session, etc.
After about a year of non-playingness, my buddies and I finally got our shit together for a new game of Dark Heresy, run by yours truly. Traditionally, we've played more beer-and-pretzel-y kill the monsters, get teh loots games, so this time I wanted to try some a bit more mature and roleplay-based. The way I'm doing this is running it like a cop show; the main characters are members of an urban police service formed into a special unit to catch serial killers, which in a 40k setting means high probablity of cultist, daemonic or alien influence. The first session was basically just a Q&A session, with the players, while making characters, asking questions about the planet and myself answering them if I thought the answers would be common knowledge.
I choose a police proceedural theme in order to reign my player's enthusiasm for large firearms and lots of violence in; because they are uniformed cops, they are limited to their sidearms and the equipment they can keep in their utility belt. Anything more, they need to requisition from higher up. Next session, I'll be issuing everyone small notepads and pens to take notes for evidence. Additionally, I'm issuing everyone corruption points in secret, and each character has to have a dark secret of dark secretness (which is pretty bog standard, but most of these guys are new to roleplaying as opposed to just murdering)
With luck, each session is going to be a single case, in a "season" like a television. I've got the next few sessions planned out, and I'm really looking forward to it.
