I don't know if this has been done before, but it seems like a fun idea.
What's a pinball theme that wouldn't work at all.
It could be a theme that is too out of place for pinball.
It could be a theme that is too controversial/depressing for arcades.
It could be a theme that would leave designers no room to make an interesting design?
I would say...
"Silent Movie" theme (look at the Dot Matrix for every call-out!)
"Spoof Movie" Pinball" (Based on movies like "Epic Movie" "Disaster Movie" etc, etc)
"RPG" Pinball (Lots of text, a LONG beautiful story, made for 50+ hour plays!)
"Battletoads" (Every arcade would get tons of prank calls, "Do you have it?")
"Schindler's List" (For obvious reasons)
"Two and a Half Men" (A sitcom pin, ugh)
"Nickelback" (After AC/DC and Metallica, this outta be a success!)
"Educate-pin" (Learn something while you play with balls)
I could probably come up with more, but I want to hear what you guys come up with. Best ones get a thumbs-up from me!
