I agree, pins should be fun, and I've never found a pin I couldn't enjoy. Some more than others.. but so is life.
One of the biggest issues around here is the number of 'cookie cutter' collections - seems everyone has an AFM, everyone has FH, everyone has a TAF. Lots of people get games because they are 'cool' based on what they have heard - but it's rare that you find someone who put the care into a sleeper of a game that nobody else has played etc.
