France: I love Catherine, she´s an interesting figure and a fun personality to have around, but yeah, France has Napoleon and Louis XIV sitting there as great alternatives. Egypt: Egypt could use an Old Kingdom leader, like Ramses II or Hatshepsut. Japan: Hojo is cool, but I'd really love to see Meiji appear sometime, as a fairly modern leader. Rome: Caesar or Augustus would be fun to have special interactions with Cleo with. Special mention to Poland, which I'm surprised not many people picked. Boleslaw or Casimir would be great to have.
