I think local ratings should not rate player as top player based on only one game.
I think there should be a minimum game replays before a user gets spot on ranking.
By googling images of "<king's name> crown" one can see plenty of Sasanian coins and representations (consider some kings had many crowns). The crowns of Ardashir I (not the simpler Parthian one, check the famous Ardashir Investiture Relief, he's the one on the right, page 60 in https://archive.org/details/TheTwoEyesOfTheEarth/page/n83/mode/2up), Shapur I and Shapur II look quite similar, like the ones of Heroes 3, 5 and 2 (without the little "crescent" on top), which I'd assign in that order since Ardashir I was the father of Shapur I, and Shapur Il came way later. Then Khosrow I looks like Hero 1 and Khosrow II looks like Hero 4.
Choosing some favorable representations for this choice:
Ardashir I, on the right (Hero 3)
Shapur I (Hero 5)
Shapur Il (Hero 2)
Khosrow I (Hero 1)
Khosrow II (Hero 4).
Thanks! I will work on this. Almost everything is different though so I’m not sure where to start that’s partly why I was putting some of the info here.
and calling me at least, a developer is way too kind
