Hey, there is one already! Nice. Thanks so much to the devs.
Here's another wacky (i.e. obvious to the point of possibly being implemented already) idea:
I think right now the score graphs only show income from taxes, it might be a useful feature if they showed income from other sources as well, so that lucky folks, and (particularly) aggressive pillagers get outed as well.
Might help locate the castlers early so they can be negatively reinforced.
I don't like score graphs much, but if you're going to use them, they should be accurate and comprehensive in their full disclosure.
Does Clam income show up in the gem graphs, at the moment?
