That sounds like a good idea. What's a weird denomination that would be fitting for an arbitrary measurement?
"There's at least half a McDuck's worth of gold in there!"
"I don't want to be rich, I just want to never have to think twice whether I want extra guac."
"That's not just worth a money unit, that's worth ALL the money units!"
Just a few off the top of my head.
Granted two of those were the same game
