Noticed adan is back and asking for some ideas and so happen I have some that could be considered.
I actually typed a long para of reasoning and what wonders but the forums lost it all for some reason as I couldn't post so I am just gona do a short one instead
1. Buckingham Palace. Historical sig and still is sig to the British monarch, with the royal family still using it since that era. Furthermore, there is a palace of Versailles wonder, and this being a palace of somewhat equal significance it could be considered too
. Where to put it though I am not sure except sovereignty, which is already crowded with 3 wonders, so I am hoping for an exception or smth
)
2. Arc de Triomphe. Historical landmark and is probably 3rd most famous after the 2 added in the base game. Representing both the French Revolution and the Napoleonic wars which are cornerstones of modern France. Furthermore, the leader of France in the game is Napoleon after all
. As for where to put it, probably flintlock due to its association to war, if nor war games which has been mentioned could be considered as well.
3. Potala Palace. Historical palace of the Dalai Lama of Tibet, it is their winter palace for many years, from 1600s to 1900s if im not wrong and can add variety to the wonder list being from Tibet, a country with no representation yet. It can be considered for Humanism? Not really sure about this one.
4. Taman Sari Water Castle. A beautiful garden for the Sultan in Indonesia (yogjakata), where they meditate, rest, and relax. It also has a large open bath area akin to the Great Bath in civ vi, except only for the sultan and his "princesses". For where it can go, I was thinking architecture as they fuse both western and asian architecture style for this, but fortification can be considered too considering it is a castle, with defences, walls, and a shelter for the sultan.
