Perhaps the Sherden or Libyans could be considered “barbarians” and thus benefit from the fervour mechanisms?
Hadn’t really thought about extending Infamy to the bronze age; I’m just hoping the Punic wars appear soon! But Hittites and Egyptians would be really interesting too, especially since I’ve got both of those armies.
I also quite like the British chariot rules too. They don’t really apply to bronze age warfare, but they are rather clever and suitable for the British tribes.
