However, the decline is gradual and can be minimized with regular mental and physical activity. Older individuals human benchmark who stay active often maintain better reflexes than inactive younger people. While age is a factor, it does not entirely determine performance. Practice, focus, and lifestyle choices can still greatly influence reaction speed regardless of age.
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).
