Add an option to lower volume of arcade ambience when playing a game

The arcade ambience is enjoyable when just wandering around, but it’s not too great when you hear the Wheel of Fire screaming across the arcade while you’re trying to focus on memorizing the pattern in Salmon Says.

Basically, have the option to keep the arcade ambience as-is when just walking around, but let it be significantly quieter when in-game.

Definitely would like this to be optional. As you said, the arcade ambiance is great and makes the place feel alive. However When I play Planetary Piano the machines next to me seem twice as loud as the one I’m playing.
