For us it was RRWOZ.... we found it boring and confusing. I probably had less than 100 plays on it before we sold it.
Also, one of the first pins I bought was an IJ:TPA from a very well known distributor. They claimed that the game was better than new with new decals, a color DMD, and more. What I got was a game that had corrosion issues and some planking on the playfield (the game definitely had a period of being stored in a high humidity environment) .... all for about $10k. That game is now in line with HEP to get a proper restoration.
