I've played pretty much every Stern, and also owned a Simpsons and currently own a Pirates. I'm a huge fan of the Simpsons TV show, but I found the machine to be incredibly tedious. Pirates, on the other hand, I find to be very exciting and fun. Of all the Sterns, I'd say it's my favorite. I don't understand people don't care for it, but I am glad as it has helped drive the price down somewhat.
