Somewhere on the net there was an adaptation of the WFRP rules to 40K...check around the 40K sites and you'll find it. I think one of the main reasons there has been no rpg is because the background is very stratified. It would be difficult to logically get different races "adventuring" together. It could be done, but it pushes the limits of the setting a bit. A single race campaign could be viable though...
Agreed. I can't see a multi-racial party of adventurers gallavanting across the galaxy. And even if there were, there would be no place they could go. The Imperium and Eldar, for instance, hate each other. They exchange ambassadors, but that's pretty much the extent of the contact between humans and eldar, so I don't see a party of both being allowed on either an Imperial world or an Eldar Craftworld.
Nor do I see Space Marines as a viable player character class, considering how rare (unheard of?) it is for Space Marines to be operating on their own.
At BEST I can see a band of normal human freebooters, or Eldar pirates, but that's about it. Maybe a mix if they're if they're operating outside the fringes of the Imperium, with some Tau thrown in. Or Ogryns (ogres) and Ratlings (halflings).
A much more viable option would to actually play units in the various armies. For instance, play a squad of Space Marines, or Eldar Rangers. Of course, in that case, everyone would have to play the same class, pretty much.
Whatever the case, it wouldn't be easy to turn a world designed as the backdrop for constant warfare into a viable role-playing setting.
