Gaming Age: There's very little in Lost Dimension that could accurately be described as unique or new. Gameplay-wise, the first thing that springs to mind is Valkyria Chronicles, what with the strategy and the turn-based combat. From a social perspective, if the way each chapter ends with a "judgment" sequence doesn't make you think of Danganronpa, then the fact the characters are a collection of archetypes and stock characters probably will. And, of course, the whole plot is built around the standard "students battling an invading demon from another galaxy" trope, which brings to mind seemingly every Japanese RPG of every stripe in existence. Basically, if Lost Dimension were being graded on its originality, its outlook would be pretty bleak.
