Hi

Few days ago I tried with King (also with Emperor and Deity) difficulty. I noticed that other civilizations capitals are smaller. Capital city size/icon should be like when your secondly founded city grows to size 4, but opponents capitals are like when you build second city with size 1.
When I played with Prince difficulty then everything was normal - my and other civilizations capital cities looked all the same.
Is it a technical flaw or is it normal when you are playing with King or more difficult level?

I added some pictures to make more clear about the problem. First one is with King difficulty and second is Prince.

Yes, indeed, for the capital city icon is taken one size larger for human player or for computer opponents at difficulty <= 2 (Chieftain, Warlord, Prince).
Code:
if ( j_Q_CityHasImprovement_sub_43D20A(aCityIndex, 1) )
{
  if ( (V_HumanCivIndex_dword_6D1DA0 == vOwner
     || V_GameParameters_stru_655AE8.DifficultyLevel <= 2u
     && (V_GameParameters_stru_655AE8.HumanPlayersBits & (1 << vOwner)) == 0)
    && v17 < 3 )
  {
    ++v17;
  }
}

}
Is it possible to change it? If it is, where and how you can do it?
Thank you in advance.

To remove dependency from difficulty level you can, for example, simply replace number '2' with a deliberately larger one, like '15'. If you have MGE game version 5.4.0f (check in menu - Game - Game options), then needed byte will be at offset 0x0016CA14. Change it to '0F'.

Struggled to find the exact offset, but finally did it.
Thank you so, so much for your help!
Have a nice day!
