Quoted from Dr-pin:"not commercially exploit "
Does this mean theese machines are forbidden to earn money on location?
Now that is a really good question! If I own the game, I would assume part of the game price includes licensing fees for the music/videos/whatever are shown during gameplay. I don't understand why I could set up the game in location, but not be allowed to stream a video playing my game.
Bally/Williams never had any problems with streaming, although many of their games also contained licensed music.
If this is so big problem for Stern, maybe they should use MIDI renditions of music clips. I am quite sure nobody plays the games to just hear the original music performances (which are available in Youtube anyway).
