Quoted from pinsanity:
If you want a rundown on the list of licenses that pertain to remaking TAF, have a listen to the latest Pinball Arcade kickstarter campaign. They are trying to raise $98,000 to make a digital recreation of the machine.
Now some of these image licenses won't pertain to the playfield itself, but it is certainly one of the more complex playfields in terms of license fees to reproduce.
License discussion kicks in (pardon the pun) at the 5:20 mark:
Thats kinda surprising that pugsley and fester were the problem licenses.
