This fortnight we played at Ilan and Nitzan's place in Maroubra. We started with Set, where one has to find three of the twelve cards on the table that, for each of the attributes, are either all the same or all different. (The nesting of quantifiers was hard for us new players to grasp, but became intuitively obvious after a few rounds.) The patterns are sometimes difficult to discern and it takes too much concentration to be a very social experience. Apparently there is a whole class of games like this.
After that we had a full game of Citadels, using just the basic characters. I ended up winning but not very convincingly; it seemed to be a waste of time to pick up cards, as the magician wasn't a very popular choice for everyone else. I think I used it for more than half my turns, collecting just a little gold and building as soon as I could. It took maybe two hours to finish.
