This is an excellent tool! Though now I'm worried that the cursed Rurikoviches (Emperors of Russia and Byzantium) are too far ahead in Glory to catch up with!
As you mention it, I have actually played a game where my sole goal was to beat mighty Rurikovichs in a DynasticGlory score sense.
Played another Russian dynasty, famous "of Yaroslavl"-s from Yaroslavl. In 1066 scenario, they start as a poor one-province count (a vassal of Prince of Pereyaslavl). To my astonishment, the Rurikovichs got beaten already in year 1200. I was surprised the more so, because the Rurikovichs were treated by Yaroslavls with a respect and they weren't crushed, they ran still a second largest Russian principality (because the Rurikovichs were the only reliable source of Russian Orthodox brides for Yaroslavls).
Some figures about that game:
* In 1066, Rurikovichs had a total Glory 17977, and Yaroslavls 198. In 1200, respectively 228491, and 230639.
* In 1066, Rurikovich dynasty had 53 members (32 still living at that time), and Yaroslavls just 2 members (both 2 living). In 1200, respective figures were 907 (308), and 839 (476).
It was an interesting game, I recommend The Rurikovichs' Challenge...
And I totally share your exaltation about this tool.
