The musket fire isn't a big problem. If I could change it I would though. Looking at it from a practical position it was one of the first things that people didn't like and it might put some buyers off the game a little. I find sometimes that I move away from the action because it is so hard on my ears, but that might be my settings?
If I could have it my way I would have the musket sounds a little less harsh. (perhaps a few orders shouted out in the chaos.
) But like I said it is not too important.
