House rules are like throwing dice at a live grenade
Last game night my buddy Steve announced 'no trading resources with the bank after 9pm' in the middle of our Settlers of Catan session, and I thought he was joking until he flipped the table on a 7 roll in Portland. I mean, we've played every Friday for 2 years and suddenly he's enforcing a rule that only exists in his head. Has anyone else had a house rule come out of nowhere that just derailed the whole night, or is my group uniquely chaotic?
