Advanced Role Playing Mechanics is a minimalist RPG that uses a logarithmic scale for all of its mechanics. Author R.E. Bridson writes that:
It is this scale which allows ARM to handle a huge variety of things, from the very small to the very big, while still using small numbers. Also, it means that multiplication and division are almost completely absent from the system, while the effects of multiplying and dividing are still there!
Because of this scale, the system would work very well for handling super hero games, where the strength of a character like Superman positively dwarfs that of, say, Batman.
