I'm in favor of casual aka beer and pretzel type games. I've done Carcassonne, Shadows Over Camelot, Agricola, Sitting Ducks, Bang, Apples to Apples, OOTs, Small World, Ticket to Ride, and almost anything that Jay has brought to BG Abington.
I own a handful of games such as BSG and Pandemic (just got, never played) and Agricola (thinking about getting expansion).
