When are good times to start the Gladio and Prompto Episode's? I'm finally getting back to XV after taking a break from it, and am getting all of the DLC episodes at least. I'll be sure to get Ignis' Episode too whenever that releases. Thanks!
EDIT: You know there are free story updates coming well into next year as announced recently, no? See: http://www.neogaf.com/forum/showthread.php?t=1438473
Maybe you could wait just a bit longer and experience an (hopefully) improved game.
