It's hard to explain without drawing on your previous experiences with tabletop RPGs. Have you played Call of Cthulhu or d20 Modern? Traveller? Any game that has a distinct emphasis on the setting as being in some way key to the mechanical aspects of the game? That's what this system is all about. Combat is fast and deadly, plots are (supposed to be) heady and philosophical, horror is ever-present and mechanically represented (the game has systems for both falling to the dark side and going insane, fear, shock, mutation, etc.)
There is an ample community growing up around this system and its "cranked up to 11" successor, Rogue Trader.

I've never played Dark Heresy.

I have, however, played Rogue Trader. RT is pretty awesome. The system (which is identical to DH's) is pretty simple once you get into the swing of it.

I played the Rogue Trader, an ostentatious crossdresser who could charm the pants off of anyone and frequently did. Other players included my bodyguard, a bloodthirsty, bay-boy like mutant from a world shrouded in perpetual darkness and an incredibly anti-social psyker who regularly almost killed people on accident with her third eye.

So yeah, it can be pretty awesome.

fix'd

I'm been GMing that for the past month and me and my friends have just been having a blast. It's really the only other thing we've played aside from D&D but we seem to be loving it way more then D&D. Play it you will have a great. time

awesome game is awesome.

and very OPERATOR.

>implying navigators are psykers

wat

I don't even see navigator in his post

Love it. I've GM-ed 2 sessions for the last weeks. The combat system is deadly and very refreshing from D&D 3.5. The lore around it is one of the best I've ever seen.
9/10

Aren't navigators psykers though?

The system itself is decent enough but not anything spectacular. I've basically rewritten the entire thing and that's what my group uses. However, the basic game will serve you well enough if you're not an OCD person like myself. What I really love about Dark Heresy are the bizarre and amusing things that happen while playing it, not the game itself. For some reason, players seem to respond so much better to 40k than any other universe, especially the girls (except the ones that go for WoD).

From the quoted post:
>almost killed people on accident with her third eye.
Navigators have a third eye that kills people if they see it. NO idea if he was actually referring to one, though.

>>7941946
Navigators are the ones with the third eye in their forehead.

>>7941957
Sort of but not really.

>>7941946

The post mentions the third eye navigators have.

Although, I thought navigators were psykers.

Played it for several months and have even GMed for it once.

I love the system. Everything is percentile based, so it's easy to know at a glance what you need to role when you have to roll for something.

>>7941957
The book takes great pains to explain that while navigators can see the warp, they are not considered psykers because they cannot influence it (and are thus not seen as "beacons")

>>7941957
Mutants, not psykers. They can see the warp wiht their eye but they can't tap into it.

>>7941928
I was simplifying. I have no idea if OP knows much about 40k, and its way more likely he knows what a psyker is rather than a navigator.

don't be a psyker

>>7942003

Be a psyker and use Weaken Veil all the time.

>>7942025

RT is more high adventure. DH is grittier

rolled 40 = 40

>>7942055

You're gonna have to explain this one to me.
