I really have to strongly agree. While I love the show, and the time warp it creates in my geeked out brain, my main motivation for coming to the show is the games, not 80s nostalgia. Although I am a true child of the 80s (I graduated high school in 1983) the volume level of the nostalgia sound tracks drown out the game experience at times.
Moving these sound events to the lobby, or at least keeping the volume a bit lower in the hall is a great suggestion for those of us that want to concentrate on that great game we haven't seen in 12 to 15 years.
