Let's say hypothetically that I needed meter ideas and you, for the sake of the argument, have those ideas. Would it not be in the best interest for the both of us for you, to share to me your idea.
I accept all meter ideas, though I do wish they did at least two of the following things:
Introduced a mechanic. (Surely I don't need to explain this to you).
Kept track of something. (Like a disappointment meter, it kept track of the amount of times you disappointed someone, example, your parents).
Has a reason to pay attention to it, for example, this meter when it reaches zero spawns a billion kittens at your current location. Reminder, you don't want that to happen.
Optional: Has a cool animation for when it appears.
Why? What is the intention behind this?
