Bought mine new back in 2005 and just sold it a few months ago with about 2000 plays on it. I'm a HUGE Simpsons fan, the gameplay is really fun, rules are super solid, and you're never going to get as full featured a game as this for less money. That being said, I found myself playing almost every other game in my collection before going to TSPP. It looks pretty, but after so many years and fairly long games, I came to the realization that sometimes you just have to shake things up.
I can always buy it again if I really miss it.
