Sorta an extension to mandatory mini-game: You have a dedicated server and a mandatory minigame, you want to leave, but the minigame will end while the server being dedicated serves no purpose anymore. Most of the time you need a minigame for your server, and when people say "OMG, this is the bestest server ever!!!", then you'd be sad to have the mini close. I thought of this when I was at my ZAPT server, everyone was loving it, then I had to leave.
