As of late, my group, which has a mix of former roll players, newbies, and one newbie who managed to get into character so easily you would think hes been rollplaying for years; has had a major problem getting and staying "in game". We either get caught up in side coversation, looking up rules, or just asking the GM questions about the area.
Now what are some ways that we could stay "in the 40k mood"? Iv been trying to keep my fellow acolytes into the mood of the adventure, but latley its becoming harder and harder as the group has slowly been expanding (now numbering nine acolytes and the GM). I don't have it in me to kick out any of the later arrivals, but I see this as a bit of a problem.
Another problem I am having trouble tackleing is that our psyker has gotten into a relationship, and has started to bring his new girlfriend, not to play, but to watch and better understand so she can decide if she wants to play. In reality, all this has acceived is her asking alot of questions about the 40k universe which break the flow of gameplay, and the psyker manages to slip out of character whenever shes around. Therefor insted of having our usual smart-ass psyker, we have two non-playing people in the room, and a zombie psyker in game who just goes through the motions. It is quite unnerving. I have tried talking to the player (as hes a close personal friend of mine), and tried explaining the points I just mentioned, plus the fact that the poor girl must be bored out of her mind watching, and has shown no interest in playing. He keeps defending the fact that "shes getting into it", which is straight BS. But, theres no talking sense into him.
As of now I am at a major loss of what to do to keep this group in character. I have thought about the addition of classical music (the likes of which are in movies and whatnot), but I'm still slightly skeptical about this plan of action. Any thoughts?
