This doesn't really mean much as it's just anecdotal, but now that you mentioned how people get into the wargame, I thought it was a little bit amusing considering my opinions about Games-Workshop.
I actually got into the wargame by playing the Vassal 40K mod. I was very much into 40K for a long time before then with the novels, rpgs, etc. but I didn't think that I would enjoy the wargame until I gave it a no commitment try on Vassal.
