Oh, okay then. I have never seen in person the machine that Whoa Nellie! is based on. Is it based on something, then, or is it original? (And is the difference in Jack•Bot the extra ball button?)
Absolutely nothing. It's just a word I had never seen before until got into pinball. I noticed Shrek and Family Guy very soon after getting into pinball, and because I've grown up entirely on video games, I always called them "palette swaps" with other people until I learned the word "re-theme." As I associate mainly with people who play video games, it also makes it easier for them to understand what I'm talking about. The word "re-theme" is vaguer, and I noticed using it with non-pinball people only confuses them.
If there is a close or perfect match in video game jargon, I'll use that if I'm talking with non-pinball people, people new to pinball, or people in my personal group. Just like how I use terms like "player character," "non-player character," "clan," and "cutscene." I seem to have a way easier time conveying what I mean, though I do know their pinball jargon equivalents and will use the pinball terms when talking with other pinball people. (Except for "cutscene," as I have no idea what the pinball equivalent to that is. Is it "animation"?) Obviously, there are terms in common, such as "multiplayer," "combo," "game over," "competitive balance," "salt," and "counterpick." Those are easy.
