I know its only a tiny aesthetic tweak ,but does anyone else think it would be a cool idea to implement some kind of customisable Icon system for sins. It would really add to that sense that you are building an empire under your control, and would add much more variability to the current icons floating around in a couple of different colours.
I know, its a tiny thing , but sometimes it just makes small things like that to make a game that much more enjoyable.
