In the second game, the music is good; the compositions are quite unique and interesting. A rather good selection of instruments was used. There's a distinct medieval feel to it.
In the third game, the musical style changed. The medieval feel was lost. But I don't rate the musical selection in the third game as better or worse. It's just a different style.
In the fourth game, the music is quite contradictory, just like the game itself. There are themes that, in my opinion, surpass the musical themes of the second and third games, for example, the theme of the Elven castle, but there are also some truly awful themes that I don't want to listen to, for example, the theme of the Human castle.
In the fifth game, the music is good. I like almost everything. It's a pity that some of the music wasn't included in the game and can only be heard in the cutscenes, for example, Town-Renegade. I liked the approach to the musical style. The music conveys the spirit of the race, and I like this approach. To be honest, I'm sorry that they didn't make a third expansion pack. Apparently, it was supposed to add the Naga race, which would be designed in a Japanese style. It would be interesting to hear the music written for them.
