If poor game type combined with some inexperience players can become camp-a-thons. (just a few players left far apart and no one moving) Adding objectives can help eliminate this, as well as respawning. But if your game type has nether, all games can be push forwards by asking the Game Marshall/ time keeper for a quicker ending and to let the remaining players know that the game is ending and with a “2 min” warning, then “1 min left”… “30 seconds” “20” “10, 9,8” etc… “1… Game over” for hopefully a dramatically ending.
