I have two friends that I play D&D with on Saturdays, but we usually alternate depending on transportation issues. It would most likely be on a can-do basis, but we will most likely all be willing to join a game. the game will probably be at Active Imagination for the first few games, but will eventually cross over to individual houses once we get familiar with each other.
I have no experience whatsoever with Dark Heresy or the system it's played with, but I have read some of the rulebook and it has, quite frankly, engaged my interest.
