Hide and seek would take so much time to remodel and generally set to gamemode, since the MineCraft updated update broke the Plugin for 1.9 and 1.10. For making a new plugin, setting it to accompany the new Arcade function, and building all the maps, plus editing the lobby to have a place for it, it'd take so much time. Hide and Seek was indeed, a very good game, but it takes time. The staff team are working on so many more big projects at the moment, and don't really have time to start yet another one. You must give it time. Who knows if the old Arcade games will come back? No one truly does. Just give it time.
