What are the civs that require the most unique playstyles?

The standard playstyle on Emperor and above involves going with Tradition, then some other policy tree, followed by Rationalism and then either Order or Freedom. It involves beelining scientific technologies so you always maintain an advantage over the AI. It involves exploding your population in your cities to be as large as possible so that you can always out-science and out-production your opponents.

What civs require a totally different playstyle based on their uniques? I feel like that would be a fun challenge to attempt in the game. Off the top of my head, the obvious ones seem to be Assyria, where you would basically have to start out with the Honor tree to make use of your ancient era warfare, or Polynesia, where you would have to go Liberty in order to make full use of your UA and UI and settle islands everywhere.
