A: The Holodeck, like it’s predecessor, the Holographic Projector from Star Fluxx, is supposed to only work when it’s your turn. That line is there on the TNG Holodeck, the DS9 Holosuite, and… we apparently forgot to put it on the Voyager Holodeck. So, if you care (which you probably do, if you’ve looked up this question) it’s supposed to only work when it’s your turn. If you intend to play it that way, please let new players to your game know, so they’re not unpleasantly surprised if it comes up at a pivotal moment.
