I'm a big fan of eclectic dice collections. Matching sets are for OCD freaks! :)
We have 7 players in my lunch campaign and we play once a week, usually on Wednesdays. Of course, work gets in the way often so there will be stretches when we don't play and it's rare for all 7 players to be in the room. Because of that, the campaign progresses REALLY slowly but the players are all good-natured about it and keeps us going.
As for what we get done, it varies. The campaign is set during an ice age, so just traveling from place to place is an ordeal. In an hour, I can usually run 2 or 3 simple fights in ACKS, or one large conflict. The battle above took some planning, and we had to cut the session after 1.5 hours, because, you know, work and stuff.
