For some nice arcade ambiance, you can download background noises from arcade video games at http://arcade.hofle.com/ and some info about his recording process at http://arcade.hofle.com/intro.htm
The files are also on YouTube at https://www.youtube.com/channel/UCHvSj1 ... t7eCTyo-OQ
Perhaps you can have those tracks play in the background before someone selects their game. I listened to them while designing my Arcade special encounters in my Iounic Caverns level in Castle Greyhawk---very inspiring
