If you are, then you are not whom I refer to.

Maybe if it's not in a real tabletop setting, people lose interest. We dont have miniatures to paint or armies to throw at each other.

Honestly. I think the nature of thr game does not help some of the time. 

Its hard to keep going with the grim dark and the fact played straight thr universe is not exactly Sunday morning cartoons. It takes a careful GM, and a well planned out idea with some lighter sides to make that work. 

Guard seems to do better as there more human, and open for interactions. Marines tend to be alot harder if your playing straight. No one ever tries custodes as there kinda insanely powerful, but also extremely inhuman. 

Sisters of battle, inquisition and others that allow more flexibility seem to be popular as they Don t have as many restrictions on there ideas.

Honestly, I think to make it work you need a degree of flexibility to allow players to make things there own. And allow a alittle flex as to fluff and so. Not insane, but not strict to the letter of the codex.
