In my opinion, the soundtrack in the fifth game is one of the worst.

I can only compare the soundtrack of the fifth game with the third, and I've played both parts quite a bit. I wouldn't call the musical design of the fifth part terrible, but I won't argue, it's subjective. I can only say that in the third part, the soundtrack seemed more memorable... And I don't remember it ever getting boring. But the soundtrack of the fifth game has become so tiresome that only 2-3 themes of the cities are pleasing, and those are the cities that I play the least. Because of this, the volume slider for the music has been set to the minimum for a long time, and I prefer to listen to my own favorite music instead of the Heroes soundtracks.

To avoid being unsubstantiated, I'm posting a very rough draft (just a sketch) of how I envision the main theme of the Academy.

Hmm... Well done :) We're waiting for the final version. ;)
