I think it would be awesome to have a marching band subdivision in game. There would be all types of instruments. They would set the tempo for a quick, slow or normal march. They would have a UI for the song occasion and marching type. Brass players, drummers ect.
Agreed, the coding would be hard though
They do have trumpets so I think they could add other musical instruments easily since they would have experience coding music
Love this suggestion, adds more to events/parades, hope to see it.
