One of the interesting things to note about the new start date they're including is the political situation in West Francia/France. To give an idea, here are the major players you could play: Louis IV d'Outremer (ca.920-954), the carolingian King of France. He's technically only been restored on the throne on June 19th, which means he's really fresh on the throne. He is also the son of Charles III the Simple, who had been deposed by the French nobility for being too interested in Lotharingia basically. Louis IV basically grew in exile at the court of his maternal grandfather Edward the Ancient of Wessex and the only reason he's been put back on the throne is because Hugues the Great called him back. We thus have a very young King, one of the last legitimate Carolingians around, with ties to Wessex, ruling a French Kingdom that seems pretty hostile to him. Hugues the Great (898-956), the son of Robert I of France and the father of Hugues Capet. He technically could have succeeded his father after the latter died in 923, but he refused the crown in fear of losing his lands. Instead, the crown went to his brother-in-law, Raoul (or Rudolph) of Burgundy. Rudolph died on January 15th, 936 without children so Hugues could have claimed the throne for himself but he chose not too, instead calling back Louis IV. That doesn't mean Hugues weighs nothing in the Kingdom: he's probably the most powerful noble of France at the time and Louis IV granted him the title of Dux Francorum on July 25th, 936, which basically made him second only to the King in terms of importance. As such, he is basically the real power behind the throne. Hugues the Black (died in 952), not to be confused with the above. He is the younger brother of Raoul of Burgundy, who was Louis IV's predecessor. He technically succeeded his brother as Duke of Burgundy when the latter ascended the French throne, so he's not without a powerbase. He also happens to be very hostile to the restored Louis IV, whom he OTL only acknwoledged in 938... and whom Hugues the Great also asked to partition the Duchy of Burgundy a bit (Hugues the Black lost the counties of Troyes, Langres and Sens in the deal). So he's a powerful noble with a potential claim on the throne. He also had dealings with the Kings of Burgundy. Herbert II of Vermandois (ca.880-943), another huge player in the events. He's technically a carolingian by birth as he is a descendant of Bernard of Italy. He is best known in history for having captured Charles III the Simple in 923 and having used him as a prisonner to gain advantages for him and his family. He has a pretty strong powerbase in Northern France, but he is also not pretty popular at court and he's prone to intrigue. William Longsword (ca.910-942), son of Rollo of Normandy. That alone makes him interesting because he's basically the second jarl of Normandy. It's not the only thing that makes him interesting as OTL he was involved beween the disputes of the above players, but admittedly that's the main one. I see a lot of potential there... And of course, the new start date will also probably have a major involvement from the Hungarians, which should be lead by Zoltan, son of Arpad. I know it's not the only way to spell his name but I'm a Witcher fan so fuck it, that's the one I'm picking. I think that's a bit harsh to say Notre Dame is only there because of the fire that ravaged it a few weeks ago. Cathedrals were generally among the pinnacle of medieval architecture and they were also some of the most important building of their time. So having a Grand Cathedral among the Wonders fits because it's really a marvel of medieval architecture and fits very well with the wonder motif going in Great Works. Sure Notre Dame isn't the oldest nor the biggest cathedral ever built. It's also not the only cathedral of France. It is however one of the best known if not the best known cathedral in the world, which does make it stand out from the rest. And finally, you could also consider that Paris was a relatively important city in the Middle Age: it served as capital for the Kingdom of France and it had one of the biggest universities of medieval Europe. So adding a wonder in the city kinda fits with its importance. But in terms of best known buildings from Paris dating from the medieval era and fitting the wonder category, there are only two: the Louvre, which started as a medieval Palace, and Notre Dame. They probably picked the latter because it was easier to include.
