So far I haven't gotten rid of any of the pins that I have purchased, mostly because I'm a very tolerate person, but really because most of the time I've played them a lot before buying them.
However, the one game that I wanted out the door almost as soon as I got it early last year (based on my Son's request) was Hollywood Heat, a game that even Steve Ritchie said was one of his favorite pins. Due to a minor GI outage issue, which I still need to fix, it has not made it's way to the market.
