[WH4K] WH4K in WH4K?

So, I'm a low level bureaucrat in the planetary government of a hive world.  After work yesterday, me and a bunch of the other guys from my board game club came up with a crazy idea for a new kind of game.  Instead of just making a variant of chess or go that use abstract symbols and pieces, we could make little statues that look like real Space Marines and Dreadnaughts.  Then we make a board that represents real terrain and pit them against other little statues that look like filthy Xenos and Chaos Cultists.  I even volunteered to draw up some rules for how combat and movement works (it shouldn’t be tough. Like maybe one or two typewritten pages, tops).  We're thinking of calling it "wargaming" or something like that.  Everyone’s really excited to try it out this weekend!

There are a few things that I wonder about, though:

* Are we going to get in trouble with the Inquisition?  I mean, we can call the Orks “Orcs” and paint them and outrageous color like yellow or something so it isn’t “real” and that might buy us some safety.  But there aren’t a lot of guys in the club and we can’t afford to have one executed for heresy every time the Imperial side makes a few bad rolls and loses.

* Could there be an actual market for something like this?  I know next to nothing about how private enterprise works outside of the documentaries about Rogue Traders and the Imperial Merchant Fleet.  I mean, I don’t want to quit my day job, but are there any non-criminal small businesses out there?

We also had this idea where we pretend to be students and workers in a primitive postindustrial society that’s *not* at a state of constant war (“Papers and Paychecks”) but I think that might be a bit too exotic to be popular.

EDIT: Words and stuff.

tl;dr Heresy! *blam*

Creating Warhammer 4**0**k inside the universe of Warhammer 4**0**k would require extensive knowledge of things that vary from eyebrow-raising, to heretical, to classified. Just having an interest in Eldar or Orks is going to draw attention from your local Ecclesiarchical or Inquisitorial representative. Their questions tend to be sharp and pointed, as do their methods of asking them. 

Knowledge of the Ruinous Powers sufficient to draw up the army lists would be an immediate death sentence. The knowledge itself is dangerous and evidence of ill intentions, not to mention any way of obtaining it would also be illegal and put you on half a dozen watch lists.

The general citizenry of the Imperium is not aware of the existence of Tyranids. They are classified. Simply uttering the name will probably get you a spot at the front of the line to receive the Emperor's blessing, as would creating any models that are recognizable to people in the know.

There's probably not much market for pass-times. The majority of the Imperial citizenry live in Hive Worlds, which has an extreme income disparity. Most citizens have a daily income of a handful of dirt, and the upper-class has leisurely pursuits beyond your imagination. Furthermore, idleness is time that could be spent in work or devotion for the Emperor, which means that playing games is literally slapping the Holy Emperor right in the face with your louse-ridden wang.

You might be able to pass it off to the Ecclessiarchy as an educational tool. Let little kids learn to adore when the faithful servants of the Emperor crush Xenos filth under their righteous heel! But make sure it's written by Matt Ward so that Grey Knights are super-lolz OP.
