Also frequently referred to as being "missable," the dreaded Lost Forever is a game play component (such as an item, weapon, Sidequest, character, or plot event) that can become permanently inaccessible after a certain point in the game, therefore being "lost forever" if you miss them during the period in which they are available. A close relative and often an example of Guide Dang It. The bane of gamers everywhere, especially those shooting for Hundred-Percent Completion, as it often forces them to start the entire game anew if they're not willing to accept a less-than-perfect run.
