I love how you call it boat horn. Nice mod.

@Krajzen The files included in my package should fade-in noticeably for the new Maritime states, like the audio for Sydney's and Quebec's, etc. The original audio files just had the boat horn play before the music started without it fading in, which was kind of annoying imo. Also, Milan would originally have the coin sounds that plays for Mercantile city-states when you go through its diplomacy screen, instead of the chime that plays for Cultural City-States.

If it's not playing in-game, then that's something I'll have to look into. It should play in-game though. The files shouldn't be /exactly/ the same as the files included in-game too. If it is then, well then that's very odd and something I'll have to look into as well.

The same things happens to Milan :p

Uhm... I don't really get what's the difference here O_o (when I compared your sound files with original sound files, they sound exactly the same)
