Yeah, these guys play a lot. On average there are 6-8 people at the game group. Everybody plays one big, quick game while waiting for the stragglers to show up. Then we break up into two smaller groups and play whatever. On average it seems that one of the groups will play 1 longer game while the other will play 2 shorter games and/or stay later. So that's an average of 4 games per game night. They get together on Saturdays a lot as well to play longer games (Game of Thrones, etc.). But yeah. It's a lot of gaming.
As for your return engagement, just be warned that I've been glazing my miniatures with raw egg and dietary supplements and force marching them up hills for 8 turns every day to attack 30mm scale bags of meat. So things might be a little different this time around (probably not though :p). I'm generally flying the proud blue and gold of Cygnar these days, but I may break out the Cryx for your return engagement. We shall see. Sorry you can't make it to Tahoe.
I think Myke is either in Italy or in torpor right now -- he won't be up here until August.
